Check Digit Verification of cas no

The CAS Registry Mumber 350049-02-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,5,0,0,4 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 350049-02:
(8*3)+(7*5)+(6*0)+(5*0)+(4*4)+(3*9)+(2*0)+(1*2)=104
104 % 10 = 4
So 350049-02-4 is a valid CAS Registry Number.

Syntheses of the optically active terpene hydroxyphenylselenides

Scianowski, Jacek,WeLniak, MirosLaw

, p. 1440 - 1447 (2009)

The optically active hydroxyphenylselenides derived from the p-menthane, carane, and pinane systems have been obtained. Two methods of hydroxyphenylselenides synthesis have been compared. The first method is based on the reaction of alkenes with N-(phenylseleno)succinimide in the presence of water, and the second from epoxides as a result of the reaction with sodium benzeneselenolate. The influence of the substrate structures on the composition of the obtained products has been demonstrated.
