Check Digit Verification of cas no

The CAS Registry Mumber 189700-13-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,9,7,0 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 189700-13:
(8*1)+(7*8)+(6*9)+(5*7)+(4*0)+(3*0)+(2*1)+(1*3)=158
158 % 10 = 8
So 189700-13-8 is a valid CAS Registry Number.

N–H insertion reaction via an iron carbenoid from α-diazophenylpropionate and its application to the formal total synthesis of stizolobinic acid

Homma, Hiroki,Miyairi, Shinichi,Mizuta, Katsumi,Saito, Hiroaki,Shinohara, Hideyuki,Uchiyama, Taketo

, (2020/10/13)

The formal total synthesis of the non-proteinogenic amino acid stizolobinic acid was accomplished relying as key step on an iron carbenoid-based N–H insertion reaction. The N–H insertion of α-diazophenylpropionate and benzylamine derivative catalyzed by tetrakis(pentafluorophenyl)porphyrin iron (III) chloride afforded the desired N–H insertion product in 79% yield. This is the first example of an N–H insertion involving α-diazophenylpropionate and an aliphatic amine catalyzed by an iron(III) porphyrin complex.

A biomimetic synthesis of stizolobinic acid

Baldwin, Jack E.,Spyvee, Mark R.,Whitehead, Roger C.

, p. 2771 - 2774 (2007/10/03)

Stizolobinic acid (1) was synthesized in a biomimetic fashion from an analogue of L-DOPA via an oxidative cleavage reaction.
