Check Digit Verification of cas no

The CAS Registry Mumber 135987-27-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,9,8 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 135987-27:
(8*1)+(7*3)+(6*5)+(5*9)+(4*8)+(3*7)+(2*2)+(1*7)=168
168 % 10 = 8
So 135987-27-8 is a valid CAS Registry Number.

TRANSITION METHAL-CATALYZED SUBSTITUTION REACTION OF ALLYLIC PHOSPHATES WITH GRIGNARD REAGENTS

Yanagisawa, Akira,Nomura, Nobuyoshi,Yamamoto, Hisashi

, p. 6017 - 6028 (2007/10/02)

SN2-selective Grignard coupling with primary allylic diphenylphosphates was successfully achieved using Ni or Fe catalyst.In sharp contrast, a catalytic amount of CuCN*2LiCl promoted a SN2'-selective coupling reaction.In the presence of the copper catalyst, stereochemically homogeneous γ-disubstituted allyl Grignard reagents reacted at the less substituted allylic terminus (α-position) with an allylic diphenylphosphate selectively without losing the double bond geometry.
