Check Digit Verification of cas no

The CAS Registry Mumber 104721-01-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,7,2 and 1 respectively; the second part has 2 digits, 0 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 104721-01:
(8*1)+(7*0)+(6*4)+(5*7)+(4*2)+(3*1)+(2*0)+(1*1)=79
79 % 10 = 9
So 104721-01-9 is a valid CAS Registry Number.

STUDIES ON THE REACTION OF PRIMARY AND SECONDARY AMINES WITH PHENYLSELENINIC ANHYDRIDE AND WITH PHENYLSELENINIC ACID

Barton, Derek H. R.,Lusinchi, Xavier,Milliet, Pierre

, p. 4727 - 4738 (1985)

The dehydrogenation under mild conditions of indolines with phenylseleninic anhydride or acid affords good yields of indoles or of 3-phenylselenenyl indoles.Tetrahydroquinoline and -isoquinoline show comparable behaviour.The dehydrogenation of primary amines gives more complicated mixtures from which nitriles and bis-2-phenylselenenylaldehydes can be isolated.
