Check Digit Verification of cas no

The CAS Registry Mumber 135747-52-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,5,7,4 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 135747-52:
(8*1)+(7*3)+(6*5)+(5*7)+(4*4)+(3*7)+(2*5)+(1*2)=143
143 % 10 = 3
So 135747-52-3 is a valid CAS Registry Number.

SYNTHESIS AND BIOLOGICAL ACTIVITY OF SOME NEW HETEROCYCLIC QUINOLINE DERIVATIVES

Awad, Ibrahim M. A.,Abdel-Rahman, Abdu E.,Bakhite, Etify A.

, p. 293 - 301 (2007/10/02)

Alkylation of 2-mercapto-3-cyano-4-aryl-5,6,7,8-tetrahydroquinoline (I) gave compounds II-IV.Cyclization of III and IV afforded thienoquinolines V and VI respectively.On diazotization of V and VI, the corresponding triazinone derivatives VII and VIII were obtained.Also, reaction of V with benzoyl chloride yielded the tetracyclic compound IX .Structures of the new compounds were established by their elemental analyses and spectral data.Some of these compounds were screened in vitro for their antibacterial activities.
