Check Digit Verification of cas no

The CAS Registry Mumber 130202-78-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,2,0 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 130202-78:
(8*1)+(7*3)+(6*0)+(5*2)+(4*0)+(3*2)+(2*7)+(1*8)=67
67 % 10 = 7
So 130202-78-7 is a valid CAS Registry Number.

New procedures for the Julia-Colonna asymmetric epoxidation: Synthesis of (+)-clausenamide

Cappi, Michael W.,Chen, Wei-Ping,Flood, Robert W.,Liao, Yong-Wei,Roberts, Stanley M.,Skidmore, John,Smith, John A.,Williamson, Natalie M.

, p. 1159 - 1160 (1998)

The oxidation of chalcone 1 to optically active epoxide 2 [a precursor of (+)-clausenamide (+)-3] may be effected using a 15-mer or 20-mer of L-leucine bound to a PEG based support; poly-L-leucines of this type may be used as immobilised catalysts in a fixed-bed reactor.
