Check Digit Verification of cas no

The CAS Registry Mumber 1240284-53-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,0,2,8 and 4 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1240284-53:
(9*1)+(8*2)+(7*4)+(6*0)+(5*2)+(4*8)+(3*4)+(2*5)+(1*3)=120
120 % 10 = 0
So 1240284-53-0 is a valid CAS Registry Number.

Enantioselective modular synthesis of cyclohexenones: Total syntheses of (+)-crypto-and (+)-infectocaryone

Franck, Geraldine,Broedner, Kerstin,Helmchen, Guenter

supporting information; experimental part, p. 3886 - 3889 (2010/12/20)

A modular synthesis of cyclohexenones is described and applied to the first enantioselective total syntheses of (+)-crypto-and (+)-infectocaryone. Key steps in the synthesis of cyclohexenones are an iridium-catalyzed allylic alkylation, nucleophilic allyl
