Check Digit Verification of cas no

The CAS Registry Mumber 74227-43-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,2 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 74227-43:
(7*7)+(6*4)+(5*2)+(4*2)+(3*7)+(2*4)+(1*3)=123
123 % 10 = 3
So 74227-43-3 is a valid CAS Registry Number.

Diazoalkane complexes and Related Compounds from Reactions of Dinitrogen Complexes of Tungsten and Molybdenum with gem-Dibromides, and from Condensation of Hydrazido(2-)-complexes with Aldehydes

Ben-Shoshan, Raphael,Chatt, Joseph,Leigh, Jeffery, G.,Hussain, Wasif

, p. 771 - 775 (1980)

The reactions of trans- with gem-dibromides lead to new diazoalkane complexes.These do not react with protonic acids, but the unique diazoalkane carbons are attacked by nucleophiles, such as LiMe, to yield diazenido-complexes, som
