Check Digit Verification of cas no
The CAS Registry Mumber 129482-56-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,4,8 and 2 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 129482-56:
(8*1)+(7*2)+(6*9)+(5*4)+(4*8)+(3*2)+(2*5)+(1*6)=150
150 % 10 = 0
So 129482-56-0 is a valid CAS Registry Number.

A new synthetic method for 4-chloromethyl-5-methyl-1,3-dioxol-2-one (1c), which is useful for preparing prodrugs, has been developed.Ene-chlorination of 4,5-dimethyl-1,3-dioxol-2-one (2) with chlorine or sulfuryl chloride afforded 4-chloro-4-methyl-5-methylene-1,3-dioxolan-2-one (3) in good yield.Compound 3 underwent allylic rearrangement to afford 1c quantitatively.The overall yield of 1c from 2 was approximately 80percent.
