Check Digit Verification of cas no

The CAS Registry Mumber 122172-49-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,2,1,7 and 2 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 122172-49:
(8*1)+(7*2)+(6*2)+(5*1)+(4*7)+(3*2)+(2*4)+(1*9)=90
90 % 10 = 0
So 122172-49-0 is a valid CAS Registry Number.

Steric effects on the regioselectivity in two-step Diels-Alder reactions of 1,2,4,5-tetrazines with 2-cyclopropylidene-4,5-dihydro-1,3-dimethyl- imidazolidine

Hartmann, Klaus-Peter,Heuschmann, Manfred

, p. 4213 - 4218 (2007/10/03)

The regioselectivity of the two-step Diels-Alder reaction of unsymmetrically substituted tetrazines 4 with 2-cyclopropylidene- imidazolidine 6 is investigated. The first reversible step of the cycloaddition affording zwitterions 7 and 8 is controlled by s
