Check Digit Verification of cas no

The CAS Registry Mumber 208102-90-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,8,1,0 and 2 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 208102-90:
(8*2)+(7*0)+(6*8)+(5*1)+(4*0)+(3*2)+(2*9)+(1*0)=93
93 % 10 = 3
So 208102-90-3 is a valid CAS Registry Number.

Synthesis of wiendendiol-A and wiedendiol-B from Labdane diterpenes

Barrero, Alejandro F.,Alvarez-Manzaneda, Enrique J.,Chahboun, Rachid

, p. 5635 - 5650 (1998)

Two efficient enantiospecific syntheses of wiedendiol-A (1) from (-)- sclareol (7), via 11-bromo-8-drimene (11) and 8-drimen-11-al (3), are reported. The first enantiospecific synthesis of wiedendiol-B (2), via 85.95- driman-11-al (26), by two alternative routes starting from 7 and (+)-cis- abienol (8) is also described. 21 prepared from protocatchhualdehyde (17) was used as somatic synthon for preparing 1 and 2.
