Check Digit Verification of cas no
The CAS Registry Mumber 2916-20-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,9,1 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 2916-20:
(6*2)+(5*9)+(4*1)+(3*6)+(2*2)+(1*0)=83
83 % 10 = 3
So 2916-20-3 is a valid CAS Registry Number.

Method for the preparation of aliphatic chloroformates
-
Page/Page column 7-8, (2008/06/13)
A method for preparing an aliphatic chloroformate comprising, introducing a mixture of at least one aliphatic hydroxyl compound, phosgene, at least one solvent, and optionally at least one organic base into a flow reactor to obtain a unidirectional flowing reaction mixture. The at least one aliphatic hydroxyl compound comprises at least one aliphatic hydroxyl group. The unidirectional flowing reaction mixture is maintained at a temperature between about 0° C. and about 60° C. to produce a single product stream comprising an aliphatic chloroformate.
