Check Digit Verification of cas no

The CAS Registry Mumber 313686-16-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,1,3,6,8 and 6 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 313686-16:
(8*3)+(7*1)+(6*3)+(5*6)+(4*8)+(3*6)+(2*1)+(1*6)=137
137 % 10 = 7
So 313686-16-7 is a valid CAS Registry Number.

Utility of 2-[4-(3-oxobenzo[f]-2H-chromen-2-yl)-1,3-thiazol-2-yl] ethanenitrile in heterocyclic synthesis

Abdelhamid, Abdou O.,Abdelaziz, Hassan M.

experimental part, p. 1719 - 1728 (2009/05/27)

(Chemical Equation Presented) Pyrazolo[4,3-d]pyrimidines, pyrazolo[4,3-d]triazolino[4,3-a]pyrimidines, 3-(2-thiazolyl)thiophenes, thiazolo[3,2-a]pyridine and pyrazolo[1,5-a]pyrimidines were synthesized from 2-[4-(3-oxobenzo[f]-2H-chromen-2-yl)-1,3-thiazol-2-yl]ethanenitrile. The newly synthesized compounds were elucidated by elemental analysis, spectral data, chemical transformation and alternative synthesis route whenever possible.
