Check Digit Verification of cas no

The CAS Registry Mumber 13721-91-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,2 and 1 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 13721-91:
(7*1)+(6*3)+(5*7)+(4*2)+(3*1)+(2*9)+(1*1)=90
90 % 10 = 0
So 13721-91-0 is a valid CAS Registry Number.

Les triorganosilylpotasium: nouvelle voie d'acces et quelques aspects de leur reactivite

Corriu, R. J. P .,Guerin, C.,Kolani, B.

, p. 973 - 979 (2007/10/02)

We report here a new procedure for the convenient and easy preparation of silylanions and especially of Me3Si-.These undergo coupling reaction with halides and α-enone in good yields.Reactions with 5-bromo-1 hexene, benzophenone and carbon dioxide provide evidence for the ability of the silylpotassium to act as monoelectron transfer reagents.The course of these reactions varies substantially with the nature of the solvent.
