Check Digit Verification of cas no

The CAS Registry Mumber 103245-09-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,2,4 and 5 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 103245-09:
(8*1)+(7*0)+(6*3)+(5*2)+(4*4)+(3*5)+(2*0)+(1*9)=76
76 % 10 = 6
So 103245-09-6 is a valid CAS Registry Number.

AN EFFICIENT SYNTHESIS OF α-KETO AMIDES VIA REACTION OF α-(N-METHYLANILINO)-ACETONITRILE WITH ESTERS FOLLOWED BY HYDROLYSIS USING COPPER (II) ACETATE

Takahashi, Kazumasa,Shibasaki, Kenichiro,Ogura, Katsuyuki,Iida, Hirotada

, p. 859 - 862 (1983)

An efficient sequence proposed for the conversion of esters to α-keto amides involves the reaction of α-(N-methylanilino)-acetonitrile with esters to afford β0hydroxy-α-cyanoenamines of which hydrolysis using copper (II) acetate gives the corresponding α-keto amides in good yields.
