79263-67-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 79263-67-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,9,2,6 and 3 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 79263-67:
(7*7)+(6*9)+(5*2)+(4*6)+(3*3)+(2*6)+(1*7)=165
165 % 10 = 5
So 79263-67-5 is a valid CAS Registry Number.

UNE NOUVELLE METHODE POUR LA PROTECTION DE LA FONCTION HYDROXYLE
Loubinoux, B.,Coudert, G.,Guillaumet, G.

Reactions of guaiacylmethyl chloride with alcohols afford the corresponding ethers in high yield ; selective protections can be achieved by phase transfer catalysis ; cleavages of the ethers by ZnBr2 are very easy.
