Check Digit Verification of cas no

The CAS Registry Mumber 20235-45-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,2,3 and 5 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 20235-45:
(7*2)+(6*0)+(5*2)+(4*3)+(3*5)+(2*4)+(1*5)=64
64 % 10 = 4
So 20235-45-4 is a valid CAS Registry Number.

Synthesis of C2-symmetric 1,4-diketones from tartaric acid dichloride

Babudri, Francesco,Fiandanese, Vito,Marchese, Giuseppe,Punzi, Angela

, p. 326 - 331 (2004)

Cross-coupling reactions of tartaric acid dichloride with organocopper reagents, derived from Grignard reagents, cuprous bromide and lithium bromide, provide a simple and straightforward method for the synthesis of C2-symmetric 1,4-diketones.
