Check Digit Verification of cas no

The CAS Registry Mumber 121740-87-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,7,4 and 0 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 121740-87:
(8*1)+(7*2)+(6*1)+(5*7)+(4*4)+(3*0)+(2*8)+(1*7)=102
102 % 10 = 2
So 121740-87-2 is a valid CAS Registry Number.

PALLADIUM CATALYZED C-ALLYLATION OF HIGHLY ACIDIC CARBO AND HETEROCYCLIC β-DICARBONYL COMPOUNDS

Prat, M.,Moreno-Manas, M.,Ribas, J.

, p. 7205 - 7212 (2007/10/02)

Highly acidic carbo and heterocyclic β-dicarbonyl compounds such as barbituric acid, 3,5-dimethyl-2H-1,2,6-thiadiazine 1,1-dioxide, cyclohexane-1,3-dione, tetronic acids, Meldrum acid and 1,2-diphenylpyrazolidine-3,5-dione are efficiently C-allylated with primary and secondary allylating agents under palladium catalysis.
