Check Digit Verification of cas no

The CAS Registry Mumber 82461-23-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,2,4,6 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 82461-23:
(7*8)+(6*2)+(5*4)+(4*6)+(3*1)+(2*2)+(1*3)=122
122 % 10 = 2
So 82461-23-2 is a valid CAS Registry Number.

Preparation of Unsaturated Hydroperoxides from N-Alkenyl-N'-p-tosylhydrazines

Bloodworth, A. J.,Courtneidge, J. L.,Curtis, Richard J.,Spencer, Michael D.

, p. 2951 - 2955 (2007/10/02)

Unsaturated hydroperoxides (R1R2CHO2H), 2-phenylpent-4-enyl hydroperoxide (1), 3-phenylhex-5-en-2-yl hydroperoxide (2), 5-methylhex-5-en-2-yl hydroperoxide (3), cyclo-oct-4-enyl hydroperoxide (18), and cyclo-oct-3-enyl hydroperoxide (24) have each been prepared from the corresponding carbonyl compound (R1R2CO) by the sequence: i, conversion to the p-tosylhydrazone (R1R2C=N-NHTs); ii, reduction with sodium cyanoborohydride at pH 3.5 to give the N'-p-tosylhydrazine (R1R2CH-NH-NHTs); and iii, oxidation with hydrogen peroxide and sodium peroxide.Isomerisation occurs in the preparation of the cyclo-octenyl hydroperoxides, particuarly if the pH falls markedly below 3.5 in the reduction step.
