Check Digit Verification of cas no

The CAS Registry Mumber 651312-17-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,1,3,1 and 2 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 651312-17:
(8*6)+(7*5)+(6*1)+(5*3)+(4*1)+(3*2)+(2*1)+(1*7)=123
123 % 10 = 3
So 651312-17-3 is a valid CAS Registry Number.

Synthesis of N-Protected 3,3-Difluoroazetidin-2-ones

Lacroix, Simon,Cheguillaume, Arnaud,Gerard, Stephane,Marchand-Brynaert, Jacqueline

, p. 2483 - 2486 (2007/10/03)

Representative N-protected 3,3-difluoroazetidin-2-ones 3 were obtained, either in one step by cycloaddition of zinc enolate 1 derived from ethyl bromodifluoroacetate onto N,N′,N″-trisubstituted hexahydro-1,3,5-triazines 2 (Schiff base trimer) in the case of 3a [N-(p-methoxybenzyl) derivative], or in two steps consisting of a Reformatsky-type reaction for the preparation of N-substituted 3-amino-2,2-difluoropropanotes 8 followed by N1-C2 cyclization under basic conditions in the cases of 3b (N-anisyl derivative) and 3c (N-benzhydryl derivative).
