160663-32-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 160663-32-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,6,0,6,6 and 3 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 160663-32:
(8*1)+(7*6)+(6*0)+(5*6)+(4*6)+(3*3)+(2*3)+(1*2)=121
121 % 10 = 1
So 160663-32-1 is a valid CAS Registry Number.

SYNTHESIS OF α-MONOCHLORO- AND α,α-DICHLORO-β-CARBONYL-SUBSTITUTED ALDEHYDES AND THEIR PROPERTIES
Guseinov, F. I.,Moskva, V. V.
, p. 384 - 390 (2007/10/02)
Acyclic and cyclic α-monochloro- and α,α-dichloro-substituted β-oxoaldehydes were obtained by selective chlorination of the enolates of β-oxoaldehydes. They readily add alcohols and thiols at the aldehyde group with the formation of stable semiacetals and
