Check Digit Verification of cas no

The CAS Registry Mumber 1381870-28-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,8,1,8,7 and 0 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1381870-28:
(9*1)+(8*3)+(7*8)+(6*1)+(5*8)+(4*7)+(3*0)+(2*2)+(1*8)=175
175 % 10 = 5
So 1381870-28-5 is a valid CAS Registry Number.

Some new derivatives of 5-aryl-,2,5-diaryland 2-ethoxycarbonyl-5-aryl- indoles

Chikvaidze, Ioseb Sh.,Barbakadze, Nana N.,Samsoniya, Shota A.

experimental part, p. 143 - 154 (2012/05/05)

Some derivatives of 5-aryl-, 2.5-diaryl-, and 2-ethoxycarbonyl-5-aryl- indoles are synthesized. Some reactions of ethyl 5-phenylindole-2-carboxylate are described. It is revealed that an α-ethoxycarbonyl group has a steric and electron-acceptor influence on indole substitution reactions. The structures of all novel compounds are confirmed by IR, UV, 1H NMR, 13C NMR and elemental analyses. ARKAT-USA, Inc.
