Check Digit Verification of cas no

The CAS Registry Mumber 839711-69-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,9,7,1 and 1 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 839711-69:
(8*8)+(7*3)+(6*9)+(5*7)+(4*1)+(3*1)+(2*6)+(1*9)=202
202 % 10 = 2
So 839711-69-2 is a valid CAS Registry Number.

Organocatalysis with proline derivatives: Improved catalysts for the asymmetric Mannich, nitro-Michael and aldol reactions

Cobb, Alexander J. A.,Shaw, David M.,Longbottom, Deborah A.,Gold, Johan B.,Ley, Steven V.

, p. 84 - 96 (2005)

Tetrazole and acylsulfonamide organocatalysts derived from proline have been synthesised and applied to the asymmetric Mannich, nitro-Michael and aldol reactions to give results that are superior to the proline-catalysed counterpart.
