Check Digit Verification of cas no

The CAS Registry Mumber 1420779-59-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,7,7 and 9 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1420779-59:
(9*1)+(8*4)+(7*2)+(6*0)+(5*7)+(4*7)+(3*9)+(2*5)+(1*9)=164
164 % 10 = 4
So 1420779-59-4 is a valid CAS Registry Number.

A silver(I)-rhodium(I) cooperative catalysis in the reaction of N′-(2-alkynylbenzylidene)hydrazide with 2-vinyloxirane

Liu, Hongliang,Liu, Gang,Qiu, Guanyinsheng,Pu, Shouzhi,Wu, Jie

, p. 1476 - 1480 (2013)

A novel and efficient route to H-pyrazolo[5,1-a]isoquinoline-1- carbaldehydes via a tandem reaction of N′-(2-alkynylbenzylidene)hydrazide with 2-vinyloxirane is described. The reaction proceeds through a silver(I)-rhodium(I) cooperative catalysis.
