Check Digit Verification of cas no

The CAS Registry Mumber 2158-93-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 8 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 2158-93:
(6*2)+(5*1)+(4*5)+(3*8)+(2*9)+(1*3)=82
82 % 10 = 2
So 2158-93-2 is a valid CAS Registry Number.

Synthesis of biaryl imino/keto carboxylic acids via aryl amide directed C-H activation reaction

Zhang, Nana,Yu, Qingzhen,Chen, Ruixue,Huang, Jianhui,Xia, Yeqing,Zhao, Kang

, p. 9464 - 9466 (2013/10/01)

A novel Pd-catalysed C-H activation reaction for the synthesis of biaryl imino/keto carboxylic acids is developed. This reaction underwent aryl amide directed C-H activation ortho-acylation followed by ring closing and ring opening processes to give a range of biaryl imino/keto carboxylic acids. Our methodology features the utilization of a cheap and green oxidant (TBHP) as well as readily available aldehydes.
