632327-16-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 632327-16-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,2,3,2 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 632327-16:
(8*6)+(7*3)+(6*2)+(5*3)+(4*2)+(3*7)+(2*1)+(1*6)=133
133 % 10 = 3
So 632327-16-3 is a valid CAS Registry Number.

Page/Page column 30; 31, (2008/06/13)
Methods for the synthesis of cyclic phosphonic acid diesters from 1,3-diols are described, whereby cyclic phosphonic acid diesters are produced by reacting a chiral 1,3-diol and an activated phosphonic acid in the presence of a Lewis acid.
