130627-13-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 130627-13-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,6,2 and 7 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 130627-13:
(8*1)+(7*3)+(6*0)+(5*6)+(4*2)+(3*7)+(2*1)+(1*3)=93
93 % 10 = 3
So 130627-13-3 is a valid CAS Registry Number.

Synthesis of 2-Substituted 1H-Benzoxazepin-5-ones
Sicker, Dieter
, p. 336 - 344 (2007/10/02)
An approach to the hitherto unknown class of 1H-benz>e>oxazepin-5-ones is given based on reduction and cyclization of appropriate acyclic ortho-nitro compounds as starting material.Thus, some 2-substituted derivatives (3a-i) were synthesized by catal
