Check Digit Verification of cas no

The CAS Registry Mumber 122039-99-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,0,3 and 9 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122039-99:
(8*1)+(7*2)+(6*2)+(5*0)+(4*3)+(3*9)+(2*9)+(1*9)=100
100 % 10 = 0
So 122039-99-0 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 (2007/10/02)

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.
