Check Digit Verification of cas no

The CAS Registry Mumber 1337541-89-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,3,7,5,4 and 1 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1337541-89:
(9*1)+(8*3)+(7*3)+(6*7)+(5*5)+(4*4)+(3*1)+(2*8)+(1*9)=165
165 % 10 = 5
So 1337541-89-5 is a valid CAS Registry Number.

Palladium-Catalyzed Synthesis of Tricyclic Indoles via a N-S Bond Cleavage Strategy

Zhang, Bo-Sheng,Wang, Fan,Gou, Xue-Ya,Yang, Ying-Hui,Jia, Wan-Yuan,Liang, Yong-Min,Wang, Xi-Cun,Li, Yuke,Quan, Zheng-Jun

supporting information, p. 7518 - 7523 (2021/10/01)

In palladium/norbornene (Pd/NBE) chemistry, the "ortho effect"has been proven to be a key factor in the process of β-carbon elimination to extrude NBE. Herein, we found that the o-iodoaniline protected by a p-methoxybenzenesulfonyl group can recover the "

Regio- and stereoselective multisubstituted enol ester synthesis

experimental part, p. 9133 - 9138 (2011/12/16)

Regio- and stereoselective cohalogenation of alkynes with NXS (X = Br, I) was achieved, and the stereoselectivity of the resulting alkenes was dependent on the substituent on the alkyne. Cohalogenation and successive cross-coupling gave multisubstituted e
