Check Digit Verification of cas no

The CAS Registry Mumber 137897-98-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,8,9 and 7 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 137897-98:
(8*1)+(7*3)+(6*7)+(5*8)+(4*9)+(3*7)+(2*9)+(1*8)=194
194 % 10 = 4
So 137897-98-4 is a valid CAS Registry Number.

Rhodium-catalyzed sulfur atom exchange reaction between organic polysulfides and sulfur

Arisawa, Mieko,Tanaka, Ken,Yamaguchi, Masahiko

, p. 4797 - 4800 (2007/10/03)

RhH(PPh3)4 and cis-1,2-bis(diphenylphosphino)ethylene (dppv) catalyze the exchange of sulfur atoms between sulfur and organic polysulfides. The exchange of dialkyl trisulfides with sulfur proceeds at a high efficiency within 5 min at room temperature yielding a mixture of organic polysulfides.
