Check Digit Verification of cas no

The CAS Registry Mumber 133546-87-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,5,4 and 6 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 133546-87:
(8*1)+(7*3)+(6*3)+(5*5)+(4*4)+(3*6)+(2*8)+(1*7)=129
129 % 10 = 9

One-step synthesis of 1,n-dicarbonyl compounds from carboxylic acid derivatives and di-Grignard reagents in the presence of transition metal catalysts

Babudri, F.,D'Ettole, A.,Fiandanese, V.,Marchese, G.,Naso, F.

, p. 53 - 58 (1991)

The transition metal catalyzed cross-coupling reaction of alkane di-Grignard reagents with carboxylic acid derivatives provides a convenient one-step synthesis of symmetrical 1,n-diketones (n8) and long-chain dicarboxylic thiol esters.
