Check Digit Verification of cas no
The CAS Registry Mumber 40943-25-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,9,4 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40943-25:
(7*4)+(6*0)+(5*9)+(4*4)+(3*3)+(2*2)+(1*5)=107
107 % 10 = 7
So 40943-25-7 is a valid CAS Registry Number.

A facile halogen exchange of active methylene chloro compounds
Bhalerao, U. T.,Raju, B. Chinna,Neelakantan, Parvathi
, p. 1197 - 1199 (2007/10/02)
An unexpected exchange of chlorine with bromine occurs during benzylation of 2-chloro-4'-hydroxy-3',5'-dimethylacetophenone (1a) with benzyl bromide.The products (2, 3 and 4) formed constitute a 60:40 mixture of chloro and bromo derivatives.A simple methodology for such an exchange in two-phase system with aq.HBr in the presence of phase transfer catalyst (PTC) is described.
