118159-66-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118159-66-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,1,5 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 118159-66:
(8*1)+(7*1)+(6*8)+(5*1)+(4*5)+(3*9)+(2*6)+(1*6)=133
133 % 10 = 3
So 118159-66-3 is a valid CAS Registry Number.

NUCLEOPHILIC SUBSTITUTION OF α-ALLENIC ALCOHOLS VIA THE MURAHASHI METHOD: 1,3-DIENES SYNTHESIS.
Fan, Changlie,Cazes, Bernard
, p. 1701 - 1704 (2007/10/02)
The alkylation of α-allenic alcohols 1 by the Murahashi procedure leads to 1,3-dienes 4.This process allows the direct nucleophilic substitution of labile or hindered α-allenic alcohols by organolithium reagents.
