Check Digit Verification of cas no

The CAS Registry Mumber 132499-66-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,2,4,9 and 9 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 132499-66:
(8*1)+(7*3)+(6*2)+(5*4)+(4*9)+(3*9)+(2*6)+(1*6)=142
142 % 10 = 2
So 132499-66-2 is a valid CAS Registry Number.

Crystal and molecular structure of the product from solvolysis of DHEA tosylate in benzyl alcohol.

Cox, Philip J.,Stewart, Neil S.,Turner, Alan B.,Howie, R. Alan

, p. 577 - 581 (1990)

The crystal and molecular structure of the product from the solvolysis of dehydroepiandrosterone (DHEA) tosylate has been determined by X-ray analysis. 1H-NMR, IR, UV, and mass spectrometry.The compound was obtained from DHEA via the 3β-tosyl derivative by refluxing in benzyl alcohol (containing dried potassium acetate) for 12 hr.X-ray analysis shows a planar cyclopropane ring at C(3), C(4) C(5), a β-orientated benzyloxy group attached to C(6) and a benzylidene group attached to C(16).Spectroscopic evidence for the presence of these features in the steroid nucleus are presented and details of the synthesis and possible mechanisms of formation are also discussed.
