The CAS Registry Mumber 1267460-67-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,7,4,6 and 0 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1267460-67:
(9*1)+(8*2)+(7*6)+(6*7)+(5*4)+(4*6)+(3*0)+(2*6)+(1*7)=172
172 % 10 = 2
So 1267460-67-2 is a valid CAS Registry Number.

Palladium-catalyzed highly regio-and stereoselective synthesis of 4-alkylidene-4 H -3,1-benzoxazines from N -Acyl-o -alkynylanilines

Saito, Takao,Ogawa, Shohei,Takei, Naoya,Kutsumura, Noriki,Otani, Takashi

, p. 1098 - 1101 (2011/04/26)

The highly regio-and stereoselective 6-exo-dig mode cyclization of N-acyl-o-alkynylanilines producing 4-alkylidene-3,1-benzoxazines occurred unpredictably by use of a proper catalyst [Pd(OAc)2] and an effective additive (acetic acid) under suit
