Check Digit Verification of cas no
The CAS Registry Mumber 55727-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,7,2 and 7 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 55727-22:
(7*5)+(6*5)+(5*7)+(4*2)+(3*7)+(2*2)+(1*2)=135
135 % 10 = 5
So 55727-22-5 is a valid CAS Registry Number.

PUSH-PULL OLEFINS FROM BIS(FORMAMIDINIUM) ETHERS
Maas, Gerhard,Feith, Bernhard
, p. 1073 - 1080 (2007/10/02)
Bis(N,N,N',N'-tetraalkyl)formamidinium ethers, readily prepared from a N,N,N',N'-tetraalkyl urea and triflic anhydride, yield push-pull olefins with activated methylene compounds H2CXY, where X, Y are CN, COOR, C6H4-4-NO2.
