Check Digit Verification of cas no

The CAS Registry Mumber 210486-35-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,0,4,8 and 6 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 210486-35:
(8*2)+(7*1)+(6*0)+(5*4)+(4*8)+(3*6)+(2*3)+(1*5)=104
104 % 10 = 4
So 210486-35-4 is a valid CAS Registry Number.

A convenient synthesis of a sterically protected 1,4-diphosphabutatriene and its pentacarbonyltungsten complexes

Ito, Shigekazu,Toyota, Kozo,Yoshifuji, Masaaki

, p. 135 - 140 (1998)

1,4-Bis(2,4,6-tri-t-butylphenyl)-1,4-diphosphabutatriene was obtained by the copper-mediated coupling reaction of 1-halo-2-phosphaethenyllithiums. The 1,4-diphosphabutatriene formed mono- and bis-pentacarbonyltungsten complexes, and the X-ray analysis of
