Check Digit Verification of cas no

The CAS Registry Mumber 100394-04-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,3,9 and 4 respectively; the second part has 2 digits, 0 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 100394-04:
(8*1)+(7*0)+(6*0)+(5*3)+(4*9)+(3*4)+(2*0)+(1*4)=75
75 % 10 = 5
So 100394-04-5 is a valid CAS Registry Number.

N-Heterocyclic Carbene-Catalysed Direct Synthesis of Cyano Esters via Cyanation-Esterification Reaction of α-Keto Esters

Zhang, Jie,Wang, Ying,Du, Guangfen,Gu, Cheng-Zhi,Dai, Bin

, p. 1211 - 1215 (2015)

The cyanation-esterification reaction of α-keto esters catalysed by N-heterocyclic carbenes (NHCs) is developed. Under the catalysis of 10 mol% 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene, aromatic and aliphatic α-keto esters reacted with ethyl cyanoformate or acetyl cyanide to produce the corresponding cyano esters with a tetrasubstituted carbon center in high yields.
