1641-58-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1641-58-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 1 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1641-58:
(6*1)+(5*6)+(4*4)+(3*1)+(2*5)+(1*8)=73
73 % 10 = 3
So 1641-58-3 is a valid CAS Registry Number.

Borazines stable to hydrolysis
Nagasawa, Koichiro
, p. 442 - 445 (2007/10/06)
In order to evaluate the steric effect of increasing the stability of the borazine ring, B-tri-2,6-xylyl- and B-trimesityl-N-trimethylborazine were prepared and subjected to Friedel-Crafts acetylation, free-radical bromination, and hydrolysis experiments.
