3216-45-3 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3216-45-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,2,1 and 6 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 3216-45:
(6*3)+(5*2)+(4*1)+(3*6)+(2*4)+(1*5)=63
63 % 10 = 3
So 3216-45-3 is a valid CAS Registry Number.

Intramolecular Didehydro-Diels-Alder Reaction for the Synthesis of Benzo- and Dihydrobenzo-Fused Heterocycles

Bober, Ashley E.,Proto, Justin T.,Brummond, Kay M.

, p. 1500 - 1503 (2017)

Using an intramolecular didehydro-Diels-Alder reaction, ene-yne substituted pyrroles, thiophenes, and furans afford functionalized indoles, benzothiophenes, and benzofurans and the corresponding dihydroaromatic products. Product selectivity for the aromatic or dihydroaromatic product is controlled by the reaction conditions, which vary depending upon the substrate.
