Check Digit Verification of cas no

The CAS Registry Mumber 170376-22-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,0,3,7 and 6 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 170376-22:
(8*1)+(7*7)+(6*0)+(5*3)+(4*7)+(3*6)+(2*2)+(1*2)=124
124 % 10 = 4
So 170376-22-4 is a valid CAS Registry Number.

Stereoselctive Total Syntheses of Conduritols-F and -A from Tricyclo2,7>undeca-4,9-dien-3,6-dione

Mgani, Quintino A.,Klunder, Antonius J. H.,Nkunya, Mayunga H. H.,Zwanenburg, Binne

, p. 4661 - 4664 (1995)

Effective syntheses of conduritols-F and A have been accomplished starting from cyclopentadiene/benzoquinone adduct 6.Key intermediates are tricyclic acetates 9 and 15 which, when subjected to flash vacuum thermolysis, afford epoxycyclohexene diacetate 10 and cyclohexadiene diacetate 17, respectively.Conduritol-F is obtained from 10 by hydrolysis while conduritol-A is produced from 17 by osmylation.In both cases the final step involves removal of the acetate groups by amidation with ammonia.
