Check Digit Verification of cas no

The CAS Registry Mumber 139116-13-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,1,1 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139116-13:
(8*1)+(7*3)+(6*9)+(5*1)+(4*1)+(3*6)+(2*1)+(1*3)=115
115 % 10 = 5
So 139116-13-5 is a valid CAS Registry Number.

Microbial transformation of diterpenes: Hydroxylation of sclareol, manool and derivatives by Mucor plumbeus

Aranda,El Kortbi,Lallemand,Neuman,Hammoumi,Facon,Azerad

, p. 8339 - 8350 (1991)

Microbial transformation of several labd-14-ene derivatives has been carried out with a Mucor plumbeus strain. Sclareol (1) (labd-14-en-8α,13β-diol) affords quantitatively a mixture of triols from which the labd-14-en-3β,8α,13β-triol (2) is obtained in high yield. Incubation of other labdane derivatives, including manool (6) [labd-8(17),14-dien-13β-ol], the corresponding 7α-hydroxy derivative (10), manoyl oxide (14) or sclareolide (15) with the same microorganism results in a mixture of various new hydroxylated and keto-derivatives.
