Check Digit Verification of cas no

The CAS Registry Mumber 1566840-86-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,6,6,8,4 and 0 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1566840-86:
(9*1)+(8*5)+(7*6)+(6*6)+(5*8)+(4*4)+(3*0)+(2*8)+(1*6)=205
205 % 10 = 5
So 1566840-86-5 is a valid CAS Registry Number.

Oxidative ortho-amino-methylation of phenols via C-H and C-C bond cleavage

Sun, Wenbo,Lin, Huacan,Zhou, Wenyu,Li, Zigang

, p. 7491 - 7494 (2014/02/14)

Initiated by CCl3Br, phenols undergo efficient ortho-selective oxidative cross dehydrogenative coupling (CDC) with trimethylamine. When tetramethylethylenediamine (TMEDA) is used instead of trimethylamine, oxidative carbon-carbon activation coupling (CAC) could occur to give the same salicylamines together with CDC by-products. These reactions are accelerated by a gold salt.
