Check Digit Verification of cas no

The CAS Registry Mumber 1402836-42-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,0,2,8,3 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1402836-42:
(9*1)+(8*4)+(7*0)+(6*2)+(5*8)+(4*3)+(3*6)+(2*4)+(1*2)=133
133 % 10 = 3
So 1402836-42-3 is a valid CAS Registry Number.

Facile synthesis for benzo-1,4-oxazepine derivatives by tandem transformation of C-N coupling/C-H carbonylation

Zhao, Xiaojia,Zhang, Jiong,Zheng, Zeqin,Xu, Runsheng

, (2017/01/24)

A tandem transformation of C-N coupling/C-H carbonylation has been developed for the synthesis of benzo-1,4-oxazepine pharmaceutically derivatives. Notably, this reaction was accomplished by various phenylamine with ally halides under carbon dioxide atmosphere employing 2-(2-dimethylamino-vinyl)-1H-inden-1-olcatalyzed. Furthermore, under the optimized conditions, various benzo-1,4-oxazepine derivatives were obtained in good yields. Finally, a plausible CuI/CuIII mechanism of C-N coupling/C-H carbonylation transformation was proposed.
