501700-22-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 501700-22-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,7,0 and 0 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 501700-22:
(8*5)+(7*0)+(6*1)+(5*7)+(4*0)+(3*0)+(2*2)+(1*2)=87
87 % 10 = 7
So 501700-22-7 is a valid CAS Registry Number.

A facile synthesis of 2-methylquinolines via Pd-catalyzed aza-Wacker oxidative cyclization
Zhang, Zuhui,Tan, Jiajing,Wang, Zhiyong
, p. 173 - 175 (2008/09/18)
(Chemical Equation Presented) A novel Pd-catalyzed Wacker-type oxidative cyclization under air is described. By using this cyclization, a series of 2-methylquinolines are readily prepared with good yields under mild conditions.
