Check Digit Verification of cas no

The CAS Registry Mumber 1265920-51-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,5,9,2 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1265920-51:
(9*1)+(8*2)+(7*6)+(6*5)+(5*9)+(4*2)+(3*0)+(2*5)+(1*1)=161
161 % 10 = 1
So 1265920-51-1 is a valid CAS Registry Number.

Unexpected heterocyclic products from cycloaddition reactions of nonsymmetrical allenyl aldoketazines with substituted alkynes

Galeta, Juraj,Man, Stanislav,Bouillon, Jean-Philippe,Potaaecek, Milan

, p. 392 - 398 (2011)

Thermally initiated cycloaddition reactions of nonsymmetrical allenyl azines 1 with alkynes or other dipolarophiles usually lead to compounds with three fused, five-membered heterocyclic rings. With alkynes with pronounced "push-pull" systems, however, th
