Check Digit Verification of cas no
The CAS Registry Mumber 455-85-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 455-85:
(5*4)+(4*5)+(3*5)+(2*8)+(1*5)=76
76 % 10 = 6
So 455-85-6 is a valid CAS Registry Number.

Preparation of 3-bromo-4-fluorobenzaldehyde and its acetals
-
, (2008/06/13)
A process for the preparation of a 3-bromo-4-fluorobenzaldehyde acetal of the formula STR1 in which R1 is methyl or ethyl, which comprises reacting a 3-bromo-4-fluoro-benzoic acid halide with ammonia to form 3-bromo-4-fluoro-benzoic acid amide, dehydrating said amide to form 3-bromo-4-fluoro-benzonitrile, reacting the nitrile with formic acid in the presence of a catalyst at a temperature between about 0° and 150° C. to form 3-bromo-4-fluorobenzaldehyde, and reacting said aldehyde with R1 OH or a derivative thereof capable of forming an acetal. The amide and nitrile are new compounds. The acetals are known intermediates in the synthesis of pyrethroid-like insecticides.
