Check Digit Verification of cas no

The CAS Registry Mumber 226722-28-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,7,2 and 2 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 226722-28:
(8*2)+(7*2)+(6*6)+(5*7)+(4*2)+(3*2)+(2*2)+(1*8)=127
127 % 10 = 7
So 226722-28-7 is a valid CAS Registry Number.

Reactions of 1,3-azaenynes with tetrazoles

Usanova,Khramchikhin,Stadnichuk

, p. 1120 - 1129 (2007/10/03)

Tetrazole and 5-substituted tetrazoles react with Schiff bases derived from α,β-acetylenic aldehydes along different pathways, depending on the substituents at the triple bond and on the nitrogen atom: (1) tetrazole addition at the triple bond, accompanied by hydrolysis of the CH=N bond; (2) base-catalyzed addition at the triple bond without hydrolysis of the CH=N bond; and (3) equilibrium addition-elimination at the CH=N bond.
