Check Digit Verification of cas no

The CAS Registry Mumber 138313-54-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,1 and 3 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 138313-54:
(8*1)+(7*3)+(6*8)+(5*3)+(4*1)+(3*3)+(2*5)+(1*4)=119
119 % 10 = 9
So 138313-54-9 is a valid CAS Registry Number.

New Syntheses of Isomerically Pure Allyl and Propargyl Cyanides by Isocyanide-Cyanide Rearrangement

Wolber, Erwin K. A.,Schmittel, Michael,Ruechardt, Christoph

, p. 525 - 532 (2007/10/02)

A new route for the synthesis of isomerically pure allyl and propargyl cyanides has been developed.Allylic amines are synthesized from the corresponding alcohols by Mitsunobu or by Overman reaction.Formylation with formic acid derivatives provides N-substituted formamides, which are dehydrated to isocyanides. 1,2-Sigmatropic rearrangement by flash pyrolysis provides the isomerically pure allyl and propargyl cyanides. Key Words: Isocyanide-cyanide rearrangment / Cyanides, allyl- and propargyl-
