35657-07-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 35657-07-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,5,6,5 and 7 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 35657-07:
(7*3)+(6*5)+(5*6)+(4*5)+(3*7)+(2*0)+(1*7)=129
129 % 10 = 9
So 35657-07-9 is a valid CAS Registry Number.

Synthesis of α-Haloalkyl Aryl Ethers from O,S-Acetals
Benneche, Tore,Undheim, Kjell
, p. 93 - 96 (2007/10/02)
α-Haloalkyl aryl ethers are prepared under mild conditions in high yileds by selective cleavage of O,S-acetals using sulfuryl chloride or bromine.The intermediate O,S-acetal is prepared from the phenol by O-alkylation using a readily accessible α-haloalkyl thioether.
