Check Digit Verification of cas no

The CAS Registry Mumber 1426892-06-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,6,8,9 and 2 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1426892-06:
(9*1)+(8*4)+(7*2)+(6*6)+(5*8)+(4*9)+(3*2)+(2*0)+(1*6)=179
179 % 10 = 9
So 1426892-06-9 is a valid CAS Registry Number.

Copper-catalyzed debenzoylative monofluoromethylation of aryl iodides assisted by the removable (2-Pyridyl)sulfonyl group

Zhao, Yanchuan,Ni, Chuanfa,Jiang, Fanzhou,Gao, Bing,Shen, Xiao,Hu, Jinbo

, p. 631 - 634 (2013/05/09)

A new method for aromatic monofluoromethylation was developed. Aryl iodides can be efficiently transformed into the corresponding monofluoromethylated products by a copper-catalyzed debenzoylative fluoroalkylation with 2-PySO 2CHFCOR and subsequent reductive desulfonylation. The (2-pyridyl)sulfonyl moiety plays an important role in the copper-catalyzed cross-coupling, and it can be removed easily through Bu3SnH-mediated desulfonylation.
