Check Digit Verification of cas no

The CAS Registry Mumber 106189-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,6,1,8 and 9 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 106189-01:
(8*1)+(7*0)+(6*6)+(5*1)+(4*8)+(3*9)+(2*0)+(1*1)=109
109 % 10 = 9
So 106189-01-9 is a valid CAS Registry Number.

SYNTHESIS OF A PROTECTED MONODEHYDRO Leu-ENKEPHALIN AND ITS HYDROGENATION CATALYZED BY CHIRAL RHODIUM COMPLEXES

Nuzillard, J. M.,Poulin, J. C.,Kagan, H. B.

, p. 2993 - 2996 (2007/10/02)

(S,S)-Z-(O)Ts-Tyr-Gly2-ΔPhe-Leu-OMe was synthesized.Some chiral rhodium complexes catalyze the reduction of the C=C bond.The stereochemistry of reduction of the ΔPhe moiety was investigated. 93 percent de could be achieved with dipamp as ligand in the cat
