Check Digit Verification of cas no

The CAS Registry Mumber 99087-52-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,9,0,8 and 7 respectively; the second part has 2 digits, 5 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 99087-52:
(7*9)+(6*9)+(5*0)+(4*8)+(3*7)+(2*5)+(1*2)=182
182 % 10 = 2
So 99087-52-2 is a valid CAS Registry Number.

Regiospecific deuteriation and tritiation of various drugs using a homogeneous rhodium trichloride catalyst

Hesk,Jones,Lockley

, p. 887 - 890 (1991)

The deuteriation and tritiation of a number of drugs containing carboxyl, amide, aralkylamine, and anilide functional groups have been investigated using homogeneous rhodium trichloride as a catalyst. Good incorporation of deuterium was observed and the regiospecificity for ortho exchange was very high for most of the drugs studied. Similarly, with tritium, good incorporation (specific activities) and regiospecificities were achieved in many cases. Satisfactory results were also obtained from the small number of heterocyclic-containing drugs that were included in the present study.
