Check Digit Verification of cas no

The CAS Registry Mumber 86318-46-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,6,3,1 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 86318-46:
(7*8)+(6*6)+(5*3)+(4*1)+(3*8)+(2*4)+(1*6)=149
149 % 10 = 9
So 86318-46-9 is a valid CAS Registry Number.

Thioketene Syntheses, VII. Substituent Effects on the Thio-Claisen Rearrangement of Alkynyl Allyl Sulfides

Schaumann, Ernst,Lindstaedt, Joerg

, p. 1728 - 1738 (2007/10/02)

Electron acceptors in the position 2 of the allyl residues in alkynyl allyl sulfides 4, 11, 15 favor the Thio-Claisen rearrangement to give thioketenes 5, 12, 16, but in position 3 impede the reaction.For the substituent on the triple bond, the sequence silyl > alkyl > alkylthio is valid.The results can be understood in terms of a zwitterionic intermediate 19 or a highly polarized transition state of the rearrangement.
