Check Digit Verification of cas no

The CAS Registry Mumber 21481-17-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,8 and 1 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21481-17:
(7*2)+(6*1)+(5*4)+(4*8)+(3*1)+(2*1)+(1*7)=84
84 % 10 = 4
So 21481-17-4 is a valid CAS Registry Number.

Regioselectivity in the rhodium catalysed 1,4-hydrosilylation of isoprene. Aspects on reaction conditions and ligands

Gustafsson, Magnus,Frejd, Torbj?rn

, p. 438 - 443 (2007/10/03)

The regioselectivity in the Rh catalysed 1,4-hydrosilylation of isoprene was investigated. Variation of solvents and temperature did not significantly affect the isomer distribution between tail-product (I) and head-product (II). The choice of ligands had
