Check Digit Verification of cas no

The CAS Registry Mumber 138043-27-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,0,4 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 138043-27:
(8*1)+(7*3)+(6*8)+(5*0)+(4*4)+(3*3)+(2*2)+(1*7)=113
113 % 10 = 3
So 138043-27-3 is a valid CAS Registry Number.

COMPETITIVE FORMATION OF TETRAHYDRO-1,3-OXAZINES BY ISOXAZOLIDINIUM SALTS RING-OPENING REACTION

Liguori, Angelo,Romeo, Giovanni,Sindona, Giovanni,Uccella, Nicola

, p. 393 - 395 (2007/10/02)

The behaviour of isoxazolidinium salts with bases has been reconsidered.Exclusive formation of tetrahydro-1,3-oxazines occurs with 5,5-disubsituted derivatives.In the presemce of a hydrogen atom at C-5 of the heterocycle, the competition of this reaction route with the Hoffman-like elimination leading to α,β-enones has been established.
