Check Digit Verification of cas no

The CAS Registry Mumber 1269183-40-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,9,1,8 and 3 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1269183-40:
(9*1)+(8*2)+(7*6)+(6*9)+(5*1)+(4*8)+(3*3)+(2*4)+(1*0)=175
175 % 10 = 5
So 1269183-40-5 is a valid CAS Registry Number.

Synthesis of 6-trifluoromethylindolo[1,2-c]quinazolines and related heterocycles using N-(2-iodophenyl)trifluoroacetimidoyl chlorides as starting material via C-H bond functionalization

Zhu, Jiangtao,Xie, Haibo,Chen, Zixian,Li, Shan,Wu, Yongming

, p. 1512 - 1514 (2011)

A mild, two-step reaction for the synthesis of 6-trifluoromethylindolo[1,2- c]quinazolines from readily available indoles and N-(2-iodophenyl) trifluoroacetimidoyl chlorides via addition-elimination/arylation is described. An array of aza-fused trifluoromethylated heterocycles can be easily assembled via Friedel-Crafts reaction/C-H bond activation by this methodology.
