116889-49-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 116889-49-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,6,8,8 and 9 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 116889-49:
(8*1)+(7*1)+(6*6)+(5*8)+(4*8)+(3*9)+(2*4)+(1*9)=167
167 % 10 = 7
So 116889-49-7 is a valid CAS Registry Number.

New Cyclic Systems from Heterocyclic 5-Substituted Tetrazole Derivatives.
Ried, Walter,Becker, Susanne
, p. 83 - 86 (2007/10/02)
The easily accessible 5-substituted tetrazole derivatives 1 and 2 react with sodium nitrite, ortho esters, some aldehydes, and bromoacetyl bromide to give the new tetrazolo-triazines 3 or 4, -pyrimidines 5 or 6, -5,6-dihydropyrimidines 7 and -diazepinones
