Check Digit Verification of cas no

The CAS Registry Mumber 2253-33-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,5 and 3 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2253-33:
(6*2)+(5*2)+(4*5)+(3*3)+(2*3)+(1*3)=60
60 % 10 = 0
So 2253-33-0 is a valid CAS Registry Number.

Preparation of α-fluoro-β-per(poly) fluoroalkyl-substituted enol ethers

Thenappan, Alagappan,Burton, Donald J.

, p. 45 - 50 (2007/10/03)

Fluorocarboethoxymethylene tri-n-butylphosphorane, Bu3P=CFCOOEt (3), reacts with per- and poly-fluoroalkyl-substituted carboxylic acid esters, ethyl formate and γ-butyrolactone to give the corresponding enol ethers, RFC (OEt)=CFCOOEt (4), in good yield. Non-activated esters failed to react with 3. With the anion derived from ethyl diethylphosphonofluoroacetate, (EtO)2P(O)CFHCOOEt (5), a mixture of 4 and β-ketoesters, RFC(O)CFHCOOEt (7), is formed.
