Check Digit Verification of cas no
The CAS Registry Mumber 130135-81-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,1,3 and 5 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 130135-81:
(8*1)+(7*3)+(6*0)+(5*1)+(4*3)+(3*5)+(2*8)+(1*1)=78
78 % 10 = 8
So 130135-81-8 is a valid CAS Registry Number.

Synthesis of Enantiomerically Pure 1-Methyl-2-alkenyl N,N-Diisopropylcarbamates from (S)- or (R)-Lactates
Schwark, Jan-Robert,Hoppe, Dieter
, p. 291 - 294 (1990)
Starting from enantiomerically pure alkyl (S)- or (R)-lactates the title compounds are obtained by Wittig olefination of 2-(N,N-diisopropylcarbamoyloxy)propanal.The reaction sequence proceeds without racemization.
