Check Digit Verification of cas no

The CAS Registry Mumber 30416-54-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,0,4,1 and 6 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 30416-54:
(7*3)+(6*0)+(5*4)+(4*1)+(3*6)+(2*5)+(1*4)=77
77 % 10 = 7
So 30416-54-7 is a valid CAS Registry Number.

Ruthenium(II)-porphyrin catalyzed selective N-imidation of aromatic nitrogen heterocycles

Jiang, Yan,Zhou, Guo-Chuan,He, Guang-Li,He, Ling,Li, Ju-An,Zheng, Shi-Long

, p. 1459 - 1464 (2007)

Ruthenium(II)-porphyrin (0.5 mol%) catalyzed N-imidations of aromatic nitrogen heterocycles with phenyl(tosylimino)iodinane under mild conditions were achieved in good yields (94%). The effects of substituent, catalyst, temperature, and solvent on the re

Sundberg, Richard J.,Ellis, James E.

, p. 573 - 576 (2007/10/02)

N-p-Toluenesulfonylimino ylides of quinoline and isoquinoline give cycloadducts with electrophilic acetylenes at 105 deg C.The adducts are spontaneously aromatized under the conditions of their formation by elimination of p-toluenesulfinic acid to give py
