Check Digit Verification of cas no

The CAS Registry Mumber 99018-40-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,1 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 99018-40:
(7*9)+(6*9)+(5*0)+(4*1)+(3*8)+(2*4)+(1*0)=153
153 % 10 = 3
So 99018-40-3 is a valid CAS Registry Number.

Hydroxyselenation of Allylic Alcohols

Cooper, Matthew A.,Ward, A. David

, p. 2327 - 2330 (2007/10/02)

Hydroxyselenation of terminal or cyclic allylic alcohols occurs with high regio- and stereoselectivity to give β,β'-dihydroxyphenylselenated adducts in high yields.A mechanism for this selectivity is proposed.The utility of these adducts is illustrated by the conversion of the hydroxyselenide (9a) to the epoxide (11) via the intermediacy of a selenone.
