Check Digit Verification of cas no

The CAS Registry Mumber 1355988-71-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,5,5,9,8 and 8 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1355988-71:
(9*1)+(8*3)+(7*5)+(6*5)+(5*9)+(4*8)+(3*8)+(2*7)+(1*1)=214
214 % 10 = 4
So 1355988-71-4 is a valid CAS Registry Number.

Difluoroalkylation/C-H Annulation Cascade Reaction Induced by Visible-Light Photoredox Catalysis

Li, Jin,Chen, Jingzhi,Jiao, Wei,Wang, Guoqiang,Li, Ying,Cheng, Xu,Li, Guigen

, p. 9992 - 10001 (2016)

We report the first example of difluoroalkylation/C-H annulation cascade reactions of cyclopropyl olefins induced by visible-light photoredox catalysis regioselectively affording partially hydrogenated naphthalenes and quinolines with a variety of difluorinated side chains. The alkylation reagent could be extended to monofluoro and trifluoro reagents, nitrile and malonate. The regioselectivity was investigated by means of density functional theory calculations.
