Check Digit Verification of cas no

The CAS Registry Mumber 138871-73-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,8,7 and 1 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 138871-73:
(8*1)+(7*3)+(6*8)+(5*8)+(4*7)+(3*1)+(2*7)+(1*3)=165
165 % 10 = 5
So 138871-73-5 is a valid CAS Registry Number.

Synthesis of cyclic valine analogs

Hungate,Chen,Starbuck

, p. 6851 - 6854 (2007/10/02)

Versatile and concise routes to both racemic and chiral cyclopentane analogs of valinol are described. These compounds are constrained analogs of a key amino acid found in the aspartyl protease inhibitors of HIV-1.
