Check Digit Verification of cas no
The CAS Registry Mumber 21905-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,9,0 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21905-86:
(7*2)+(6*1)+(5*9)+(4*0)+(3*5)+(2*8)+(1*6)=102
102 % 10 = 2
So 21905-86-2 is a valid CAS Registry Number.

PREPARATION OF CINNOLINE-3,4-DICARBONITRILE AND -DICARBOXYLIC ACID
Ames, D. E.,Bull, D.
, p. 2489 - 2492 (2007/10/02)
Attempts to prepare cinnoline-3,4-dicarboxylic acid from 3,4-dimethylcinnoline failed owing to the unreactivity of the 3-Me group.Successive treatment of 3-bromo-4-chlorocinnoline with sodium toluene-p-sulphinate and potassium cyanide in dimethylformamide (DMF) gave 4-toluene-p-sulphonylcinnoline-3-carbonitrile and then cinnoline-3,4-dicarbonitrile (82percent).Hydrolysis yielded cinnoline-3,4-dicarboxylic acid (53percent).Cinnoline-3,4-dicarbonitrile undergoes nucleophylic displacement of either the 4- or the 3-cyano group by ammonia or amine to give 4-amino- and 4-benzylaminocinnoline-3-carbonitrile but 3-dimethylamino-cinnoline-4-carbonitrile.
