Check Digit Verification of cas no

The CAS Registry Mumber 13534-08-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,3 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13534-08:
(7*1)+(6*3)+(5*5)+(4*3)+(3*4)+(2*0)+(1*8)=82
82 % 10 = 2
So 13534-08-2 is a valid CAS Registry Number.

A General Synthesis of N-Substituted 2-Azaadamantanes and Their 4,8-Disubstituted Derivatives

Henkel, James G.,Faith, William C.,Hane, Jeffrey T.

, p. 3483 - 3486 (1981)

A general synthesis of N-substituted 2-azaadamantanes (1) is reported, along with the corresponding 4,8-dihydroxy derivatives (2).The synthesis offers the advantage of the use of inexpensive and readily available starting material.Dione 3, obtained by decarboxylation of Meerwein's ester, is converted to diene 4 by Bamford-Stevens-type elimination of the corresponding ditosylhydrazone.Epoxidation of 4 affords diepoxide 12, which reacts with primary amines to form the 2-azaadamantyl skeleton 2.Removal of the hydroxyl groups to give 1 is accomplished by using SOCl2 and then LiAlH4.
