31774-46-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 31774-46-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,1,7,7 and 4 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 31774-46:
(7*3)+(6*1)+(5*7)+(4*7)+(3*4)+(2*4)+(1*6)=116
116 % 10 = 6
So 31774-46-6 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.
