Check Digit Verification of cas no

The CAS Registry Mumber 69993-40-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,9,9 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 69993-40:
(7*6)+(6*9)+(5*9)+(4*9)+(3*3)+(2*4)+(1*0)=194
194 % 10 = 4
So 69993-40-4 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.
