Check Digit Verification of cas no

The CAS Registry Mumber 1345691-07-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,4,5,6,9 and 1 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1345691-07:
(9*1)+(8*3)+(7*4)+(6*5)+(5*6)+(4*9)+(3*1)+(2*0)+(1*7)=167
167 % 10 = 7
So 1345691-07-7 is a valid CAS Registry Number.

Synthesis and anticancer activity of some new series of 1, 4-dihydropyridine derivatives

Surendra Kumar,Idhayadhulla,Jamal Abdul Nasser,Murali

, p. 1140 - 1144 (2011/10/05)

A series of 1,4-dihydropyridine derivatives 1a-c have been prepared from 4-substituted aromatic aldehyde, ethyl acetoacetate and ammonium hydroxide following Hantzsch method. The compounds 1a-c have been reacted with semicarbazide to give the compounds 2a-c. The compounds 1a-c have been reacted with thiosemicarbazide to give the compounds 3a-c. The structures of synthesized compounds are confirmed by IR, 1H and 13C NMR, mass spectrometry and elemental analyses. The newly synthesized compounds have been screened for preliminary anti-cancer activity against HepG2 (Liver), Hela (Cervical) and MCF-7 (Breast) cancer cells. The compound 2a is highly active against HepG2, MCF-7 and 3a is highly active against Hela (Cervical) and these have been selected for advanced preclinical development.
