Check Digit Verification of cas no

The CAS Registry Mumber 93178-05-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,3,1,7 and 8 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 93178-05:
(7*9)+(6*3)+(5*1)+(4*7)+(3*8)+(2*0)+(1*5)=143
143 % 10 = 3
So 93178-05-3 is a valid CAS Registry Number.

Synthesis of Deuterium-Labeled Sesquiterpene Lactones Isolated from Inula helenium L.

Schaeffer, Marcel,Stampf, Jean-Luc,Benezra, Claude

, p. 6106 - 6113 (2007/10/02)

Reduction of the vinyl sulfoxides 9 and 10 derived from isoalantolactone (1) and alantolactone (2) with NaBD4 yielded deuterium-labeled lactones 11 and 12.Amalgam reduction of sulfides 7 and 8 or sulfoxides 9 and 10 gave labeled products but not the expected deuterated lactones 11 and 12.Satisfactory deuteration of alantolactone 2 could be achieved by CF3COOD hydrolysis of (tributylstannyl)alantolactone (23) obtained in four steps from alantolactone 2.
