Check Digit Verification of cas no
The CAS Registry Mumber 133634-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,3,6,3 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 133634-31:
(8*1)+(7*3)+(6*3)+(5*6)+(4*3)+(3*4)+(2*3)+(1*1)=108
108 % 10 = 8
So 133634-31-8 is a valid CAS Registry Number.

Preparation and utilization of chiral dihydropyridines. Synthesis of chiral indoloquinolizines and benzoquinolizines
Mangeney,Gosmini,Raussou,Commercon,Alexakis
, p. 1877 - 1888 (2007/10/02)
An asymmetric synthesis of 3-formyl-1,4-dihydropyridines is described that entails the addition of organocopper reagents to activated 3- imidazolidinylpyridine, prepared with chiral diamines. The activator can be a chloroformate or an acid chloride. The m
