Check Digit Verification of cas no

The CAS Registry Mumber 7622-75-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,2 and 2 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7622-75:
(6*7)+(5*6)+(4*2)+(3*2)+(2*7)+(1*5)=105
105 % 10 = 5
So 7622-75-5 is a valid CAS Registry Number.

General and efficient route for the synthesis of 3,4-disubstituted coumarins via Pd-catalyzed site-selective cross-coupling reactions

Zhang, Liang,Meng, Tianhao,Fan, Renhua,Wu, Jie

, p. 7279 - 7286 (2008/02/11)

(Chemical Equation Presented) Palladium-catalyzed site-selective cross-coupling reactions of 3-bromo-4-trifloxycoumarin or 3-bromo-4- tosyloxycoumarin provide an efficient and facile route for the synthesis of 3,4-disubstituted coumarins, which include 3,
