Check Digit Verification of cas no

The CAS Registry Mumber 870073-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,0,0,7 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 870073-17:
(8*8)+(7*7)+(6*0)+(5*0)+(4*7)+(3*3)+(2*1)+(1*7)=159
159 % 10 = 9
So 870073-17-9 is a valid CAS Registry Number.

Isotope labeled 'HEA/HEE' moiety in the synthesis of labeled HIV-protease inhibitors - Part II

Ekhato, I. Victor,Liao, Yuan,Plesescu, Mihaela

, p. 179 - 193 (2007/10/03)

[2H5]-Amprenavir and [2H 5]-saquinavir have been prepared from a common labeled precursor (1S, 2S)-(1-oxiranyl-2-[2H5]phenylethyl)-carbamic acid tert-butyl ester, 1. Both of these compounds are in the 'HEA' class of HIV protease inhibitors. [2H5]-Indinavir, a representative of the 'HEE' group of protease inhibitors, has also been synthesized. In the case of indinavir, 1S-(2,2-dimethyl-8, 8a-dihydro-3aH-indeno-[1,2-d]-oxazol-3R-yl)-2- oxiranylmethyl-3-[2H5]phenylpropan-1-one, 11, provided the [phenyl-2H5]-HEE core structure for synthesis of the desired labeled compound.
