Check Digit Verification of cas no

The CAS Registry Mumber 1311931-02-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,1,1,9,3 and 1 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1311931-02:
(9*1)+(8*3)+(7*1)+(6*1)+(5*9)+(4*3)+(3*1)+(2*0)+(1*2)=108
108 % 10 = 8
So 1311931-02-8 is a valid CAS Registry Number.

Regio- and chemoselective C-H chlorination/bromination of electron-deficient arenes by weak coordination and study of relative directing-group abilities

Sun, Xiuyun,Shan, Gang,Sun, Yonghui,Rao, Yu

, p. 4440 - 4444 (2013)

It's all relative: A practical and efficient PdII-catalyzed regio- and chemoselective chlorination/bromination has been developed for the facile synthesis of a broad range of aromatic chlorides. The reaction demonstrates excellent reactivity, good functional-group tolerance, and high yields. A preliminary study was conducted to evaluate relative directing-group abilities of various functionalities. Copyright
