1316315-38-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1316315-38-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,6,3,1 and 5 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1316315-38:
(9*1)+(8*3)+(7*1)+(6*6)+(5*3)+(4*1)+(3*5)+(2*3)+(1*8)=124
124 % 10 = 4
So 1316315-38-4 is a valid CAS Registry Number.

Synthesis of deuterium-labelled etravirine
Wang, Wei,Wu, Wenchao,Shen, Zucheng,Chen, Liqin
, p. 371 - 373 (2011)
This study describes the synthesis of deuterium-labelled etravirine. Etravirine labelled with six deuteriums was prepared in eight steps starting from phenol with excellent chemical purity and isotopic enrichment. It provides important internal standard f
