Check Digit Verification of cas no

The CAS Registry Mumber 1372788-46-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,7,2,7,8 and 8 respectively; the second part has 2 digits, 4 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1372788-46:
(9*1)+(8*3)+(7*7)+(6*2)+(5*7)+(4*8)+(3*8)+(2*4)+(1*6)=199
199 % 10 = 9
So 1372788-46-9 is a valid CAS Registry Number.

Direct arylation under catalysis of an oxime-derived palladacycle: Search for a phosphane-free method

Zhang, Guofu,Zhao, Xiaobao,Yan, Yunbing,Ding, Chengrong

, p. 669 - 672 (2012/03/27)

A phosphane-free method for the direct arylation of benzothiazole by employing oxime-derived palladacycle 1 as a catalyst was developed. The new catalyst system can be used for 2-arylations by using aryl bromides and iodides. In addition, this method is especially suitable for the intramolecular direct coupling of bromo-and iodoamides, as well aschloroamides, to achieve a rapid synthesis of benzo[c]phenanthridine alkaloids. Direct arylation reactions under catalysis of an oxime-derived palladacycle were investigated. This phosphane-free method is applicable for the 2-arylation of benzothiazole and is especially suitable for the intramolecular direct coupling of bromo-and iodoamides, as well as chloroamides, to achieve rapid synthesis of benzo[c]phenanthridine alkaloids.
