Check Digit Verification of cas no
The CAS Registry Mumber 2157-16-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 7 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 2157-16:
(6*2)+(5*1)+(4*5)+(3*7)+(2*1)+(1*6)=66
66 % 10 = 6
So 2157-16-6 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.
A safe and efficient procedure to prepare alkyl and alkoxyalkyl chlorides and dichlorides by catalytic decomposition of the corresponding alkyl and alkoxyalkyl chloroformates and bischloroformates with hexabutylguanidinium chloride
Violleau,Thiebaud,Borredon,Le Gars
, p. 367 - 373 (2007/10/03)
Small amounts of hexabutylguanidinium chloride (0.01 mol%) decomposes pure chloroformates or bischloroformates with different lengths of carbon chains by a semicontinuous process to diminish run-away risk, leading to chloride compounds with high yield and purity.
Oxyformamidates
-
, (2008/06/13)
Compounds of the formula STR1 WHEREIN A is a linking group, X is an O--CO-- or --SO2 -- group and n is at least 2, are prepared from the corresponding N',N'-disubstituted hydrazides by quaternization and treatment with alkali or reaction with an alkylene epoxide or from the corresponding compound wherein n = 1 and A is a polymerizable group by polymerization. The compounds are unstable to heat and may be used as cross-linking agents for polymers or as chain-extending agents, bonding agents or adhesives.
