Check Digit Verification of cas no

The CAS Registry Mumber 34169-77-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,1,6 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 34169-77:
(7*3)+(6*4)+(5*1)+(4*6)+(3*9)+(2*7)+(1*7)=122
122 % 10 = 2
So 34169-77-2 is a valid CAS Registry Number.

STEREO- AND REGIOSELECTIVITY OF THE CATALYTIC SYSTEM MoCl5/SiO2-SnMe4 IN THE REACTION OF METATHESIS AND COMETATHESIS OF OLEFINS AND THEIR FUNCTIONAL DERIVATIVES

Bykov, V. I.,Butenko, T. A.,Finkel'shtein, E. Sh.

, p. 151 - 155 (2007/10/02)

It was shown that the catalytic system MoCl5/SiO2-SnMe4 has almost 100percent regioselectivity with respect to olefins.The stereoselectivity of the system is not a function of the length of the α-olefin chain, temperature, or addition of functional groups (COOEt, Cl).Addition of pentachlorophenoxy and 8-hydroxyquinolyl ligands significantly reduces the activity of the catalytic system with a slight increase in the stereoselectivity with respect to the cis-isomer.
