Check Digit Verification of cas no

The CAS Registry Mumber 145662-43-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,6,6 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 145662-43:
(8*1)+(7*4)+(6*5)+(5*6)+(4*6)+(3*2)+(2*4)+(1*3)=137
137 % 10 = 7
So 145662-43-7 is a valid CAS Registry Number.

, p. 561 - 572 (2015/05/20)

Hypervalent iodine mediated decarboxylative halogenation of indoledicarboxylic acid derivatives was studied. The treatment of 1-methylindole-2,3-dicarboxylic acid with phenyliodine diacetate (PIDA) in the presence of lithium bromide gave 1-methyl-3,3-brom

Decarboxylative bromination of indole-2,3-dicarboxylic acids using oxone or can in the presence of lithium bromide

Umemoto, Hideaki,Umemoto, Misako,Ohta, Chiaki,Dohshita, Masashi,Tanaka, Hiroki,Hattori, Syo,Hamamoto, Hiromi,Miki, Yasuyoshi

experimental part, p. 2845 - 2850 (2010/04/29)

The treatment of l-methylindole-2,3-dicarboxylic acid with Oxone and lithium bromide produced 3,3-dibromo-l-methyloxindole. However, the reaction of 1-benzenesulfonylindole-2,3-dicarboxylic acid with Oxone and lithium bromide afforded l-benzenesulfonyl-2,
