Check Digit Verification of cas no

The CAS Registry Mumber 144969-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,4,9,6 and 9 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 144969-67:
(8*1)+(7*4)+(6*4)+(5*9)+(4*6)+(3*9)+(2*6)+(1*7)=175
175 % 10 = 5
So 144969-67-5 is a valid CAS Registry Number.

The Synthesis of Methyl (15S)-16-Hydroxydehydroabietate and Its (15R)-Epimer

Matsumoto, Takashi,Imai, Sachihiko,Hayashi, Noriaki

, p. 2405 - 2412 (1988)

In order to elucidate the absolute configuration of C-15 in natural 16-hydroxydehyroabietic acid, a metabolite of (+)-dehydroabietic acid in rabbits, methyl (+)-dehydroabietate was transformed into methyl (15S)-16-hydroxy-8,11,13-abietatrien-18-oate (3a) and its (15R)-epimer (3b).The synthetic 3a was identical with a methyl ester derived from the natural acid.Thus, the absolute configuration of C-15 in natural 16-hydroxydehydroabietic acid was conclusively assigned as an S-configuration.
