Check Digit Verification of cas no

The CAS Registry Mumber 38224-24-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,2,2 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 38224-24:
(7*3)+(6*8)+(5*2)+(4*2)+(3*4)+(2*2)+(1*4)=107
107 % 10 = 7
So 38224-24-7 is a valid CAS Registry Number.

A general and efficient approach to 2H-indazoles and 1H-pyrazoles through copper-catalyzed intramolecular N-N bond formation under mild conditions

Hu, Jiantao,Cheng, Yongfeng,Yang, Yiqing,Rao, Yu

, p. 10133 - 10135 (2011/10/09)

A new efficient copper-catalyzed intramolecular amination reaction has been developed to readily synthesise a wide variety of multi-substituted 2H-indazole and 1H-pyrazole derivatives from easily accessible starting materials under mild conditions. A highly selective ligand for estrogen receptor β was prepared in three steps by employing this method. The Royal Society of Chemistry 2011.
