Check Digit Verification of cas no

The CAS Registry Mumber 499142-34-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,9,1,4 and 2 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 499142-34:
(8*4)+(7*9)+(6*9)+(5*1)+(4*4)+(3*2)+(2*3)+(1*4)=186
186 % 10 = 6
So 499142-34-6 is a valid CAS Registry Number.

Synthesis and reactions of some new heterocyclic compounds containing cycloalka[e]thieno[2,3-b]pyridine Moiety

Al-Sehemi, Abdullah G.,Bakhite, Etify A.

, p. 975 - 985 (2007/10/03)

Hydrolysis of ethyl 3-amino-4-aryl-cycloalka[e]thieno[2,3-b]pyridine-2- carboxylates (3a-d) gave the corresponding o-aminocarboxylic acids 4 a-d. Heating the latter compounds (4a-d) with acetic an hydride furnished the oxazinone derivatives 5a-d which, in
