Check Digit Verification of cas no
The CAS Registry Mumber 18719-42-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,8,7,1 and 9 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 18719-42:
(7*1)+(6*8)+(5*7)+(4*1)+(3*9)+(2*4)+(1*2)=131
131 % 10 = 1
So 18719-42-1 is a valid CAS Registry Number.

A method has been worked out to synthetize hitherto unknown 5-(2-chloroalkyl) Meldrum's acids 4 starting from easily accessible 2-chlorocarboxylic acid chlorides 1 in a two-step reaction. Reactions of dihaloethane and Meldrum's acid in the presence of potassium carbonate and the usefulness of compounds 4 are also presented.
