21372-83-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21372-83-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,3,7 and 2 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 21372-83:
(7*2)+(6*1)+(5*3)+(4*7)+(3*2)+(2*8)+(1*3)=88
88 % 10 = 8
So 21372-83-8 is a valid CAS Registry Number.

Alcoholysis of fluoroform
Miloserdov, Fedor M.,Grushin, Vladimir V.
, p. 105 - 109 (2015/03/03)
Fluoroform (CHF3) reacts with alkali metal alkoxides MOR (M = Na, K) in the corresponding alcohols ROH (R = Me, Et, i-Pr, t-Bu, and Allyl) at 80-120°C to give orthoformate esters HC(OR)3 in 55-90% yield. Particularly notable is the f
