The chemical compound "(3aR*,4R*,7aR*)-3a-ethoxycarbonyl-4-methoxy-1-methyl-2,3-dioxo-7a-phenyl-6-trimethylsilyloxy-2,3,3a,4,7,7a-hexahydroindole" is a complex organic molecule with a unique structure. It features a hexahydroindole core, which is a type of indole ring system that has been reduced to contain six hydrogen atoms in its structure. The compound is characterized by the presence of several functional groups, including an ethoxycarbonyl group at the 3a position, a methoxy group at the 4 position, and a trimethylsilyloxy group at the 6 position. Additionally, it has a 1-methyl group and a 7a-phenyl group, which contribute to its structural diversity. The compound's chiral centers are indicated by the asterisks (*), specifying the absolute configuration at the 3a, 4, and 7a positions as R*, meaning that the substituents are arranged in a specific three-dimensional orientation. (3aR*,4R*,7aR*)-3a-ethoxycarbonyl-4-methoxy-1-methyl-2,3-dioxo-7a-phenyl-6-trimethylsilyloxy-2,3,3a,4,7,7a-hexahydroindole is likely to be of interest in the fields of organic chemistry and medicinal chemistry due to its potential applications in the synthesis of pharmaceuticals or other bioactive molecules.

Check Digit Verification of cas no

The CAS Registry Mumber 86236-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,2,3 and 6 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 86236-60:
(7*8)+(6*6)+(5*2)+(4*3)+(3*6)+(2*6)+(1*0)=144
144 % 10 = 4
So 86236-60-4 is a valid CAS Registry Number.

FACTORS CONTROLLING C=C VS. C=O ATTACK IN CYCLOADDITION OF A 1,3-DIENE TO AN AMBIDENT DIENOPHILE. DIELS-ALDER REACTION OF 2-PHENYL-Δ2-PYRROLINE-4,5-DIONES

Sano, Takehiro,Toda, Jun,Tsuda, Yoshisuke

, p. 356 - 359 (2007/10/02)

The cycloaddition using an enone as a dienophile is on a balance with the normal C=C attack (ene-addition) and the unusual C=O attack (one-addition) of a diene.Steric hindrance on the C=C (caused by such phenomena as restricted free rotation of the substituent on C=C) retards the C=C attack, thus increasing the ratio of one-addition.Lewis acids greatly increase not only the reactivity of C=O but also the ratio of one-addition.KEYWORDS --- 1-methoxy-3-trimethylsilyloxybutadiene; Diels-Alder reaction; dioxopyrroline; ambident dienophile; ene-addition; one-addition; steric hindrance; Lewis acid
