Check Digit Verification of cas no

The CAS Registry Mumber 1603838-18-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,3,8,3 and 8 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1603838-18:
(9*1)+(8*6)+(7*0)+(6*3)+(5*8)+(4*3)+(3*8)+(2*1)+(1*8)=161
161 % 10 = 1
So 1603838-18-1 is a valid CAS Registry Number.

Iridium(I)-catalyzed direct C-H bond alkylation of the C-7 position of indolines with alkenes

Pan, Shiguang,Ryu, Naoto,Shibata, Takanori

, p. 929 - 933 (2014/04/03)

A cationic iridium-catalyzed C-7 alkylation of N-substituted indoline derivatives with various alkenes has been developed. A variety of 7-alkylindolines were obtained in moderate to high yields. This protocol relies on the use of the carbonyl group on the nitrogen atom of indoline as a directing group and it is potentially applicable to the large-scale synthesis of 7-alkylindoles.
