Check Digit Verification of cas no

The CAS Registry Mumber 74571-29-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,5,7 and 1 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74571-29:
(7*7)+(6*4)+(5*5)+(4*7)+(3*1)+(2*2)+(1*9)=142
142 % 10 = 2
So 74571-29-2 is a valid CAS Registry Number.

N-carbamoyl-4-diphenylphosphino-2-diphenylphosphinomethylpyrrolidines(CAPP). Efficient new chiral ligands for asymmetric hydrogenation

Ojima, Iwao,Yoda, Noriko

, p. 1051 - 1054 (2007/10/02)

A series of N-(N′-substituted carbamoyl)-4-diphenylphosphino-2-diphenylphosphinomethylpyrrolidines (CAPP) was prepared, which exhibited excellent stereoselectivity in the asymmetric hydrogenation of α-acetamidocinnamic acid derivatives and itaconic acid as chiral ligand of the rhodium(I) catalyst.
