27578-74-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 27578-74-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,7,5,7 and 8 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 27578-74:
(7*2)+(6*7)+(5*5)+(4*7)+(3*8)+(2*7)+(1*4)=151
151 % 10 = 1
So 27578-74-1 is a valid CAS Registry Number.

Preparation of acyclic and cyclic phosphoric triamides and diamido esters
Wan, Huijie,Modro, Tomasz A.
, p. 1227 - 1231 (1996)
Using phosphoryl chloride as a substrate, a series of N-bis(2-chloroethyl)phosphoric triamides (and diamido esters) was prepared. These acyclic products were cyclized to the 1,3,2-diazaphospholidine derivatives, which, in turn, could be cyclized again to
