Check Digit Verification of cas no

The CAS Registry Mumber 92151-39-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,2,1,5 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 92151-39:
(7*9)+(6*2)+(5*1)+(4*5)+(3*1)+(2*3)+(1*9)=118
118 % 10 = 8
So 92151-39-8 is a valid CAS Registry Number.

Direct organocatalytic asymmetric heterodomino reactions: The Knoevenagel/Diels-Alder/epimerization sequence for the highly diastereoselective synthesis of symmetrical and nonsymmetrical synthons of benzoannelated centropolyquinanes

Ramachary,Anebouselvy,Chowdari, Naidu S.,Barbas III, Carlos F.

, p. 5838 - 5849 (2004)

Amino acids and amines have been used to catalyze three component hetero-domino Knoevenagel/Diels-Alder/epimerization reactions of readily available various precursor enones (1a-1), aldehydes (2a-p), and 1,3-indandione (3). The reaction provided excellent
