Check Digit Verification of cas no

The CAS Registry Mumber 155899-89-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,8,9 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 155899-89:
(8*1)+(7*5)+(6*5)+(5*8)+(4*9)+(3*9)+(2*8)+(1*9)=201
201 % 10 = 1
So 155899-89-1 is a valid CAS Registry Number.

A short asymmetric synthesis of (+)-nonactic acid and (-)-8-epi-nonactic acid induced by a chiral sulfoxide group

Solladie,Dominguez

, p. 3898 - 3901 (2007/10/02)

A short enantioselective synthesis of (+)-(2S,3S,6R,8R)-nonactic acid and (-)-(2R,3R,6S,8R)-epinonactic acid is described. The key step was the stepwise stereoselective reduction of the triketo sulfoxide B without any protective group on the different carbonyls.
