42164-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 42164-31-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,1,6 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 42164-31:
(7*4)+(6*2)+(5*1)+(4*6)+(3*4)+(2*3)+(1*1)=88
88 % 10 = 8
So 42164-31-8 is a valid CAS Registry Number.

A Stereochemical Investigation of 1,3-Diphenyl-4-methyl-1,3-diazolidines and its Related Compounds via NMR
Nishiyama, Tomihiro,Nanno, Yukio,Yamada, Fukiko
, p. 1773 - 1776 (2007/10/02)
Four 1,3-diphenyl-4-methyl-1,3-diazolidines and two isomeric 2,5-diphenyl-3-methyl-1,2,5-thiadiazolidine 2-oxides were prepared.The pmr and cmr spectra of these compounds were obtained.On the basis of the chemical shifts due to the γ- and δ-effects, the stereochemical structures are discussed.
