Check Digit Verification of cas no

The CAS Registry Mumber 81331-45-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,3,3 and 1 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 81331-45:
(7*8)+(6*1)+(5*3)+(4*3)+(3*1)+(2*4)+(1*5)=105
105 % 10 = 5
So 81331-45-5 is a valid CAS Registry Number.

SELONES AS INTERMEDIATES IN THE PREPARATION OF EXTREMELY STERICALLY HINDERED MOLECULES

Guziec, Frank S.,Sanfilippo, Lynn James,Murphy, Christopher J.,Moustakis, Christine A.,Cullen, Edward R.

, p. 4843 - 4852 (2007/10/02)

The preparation and reactions of selones, selenium analogues of ketones, are described with particular emphasis on their utility in the preparation of extremely sterically hindered molecules.Mechanistic questions related to these reactions are discussed and evidence for "active selenium" is presented.Selenophilic additions of organometallic compounds to selones are also reported.
