Check Digit Verification of cas no

The CAS Registry Mumber 1443988-41-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,3,9,8 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1443988-41:
(9*1)+(8*4)+(7*4)+(6*3)+(5*9)+(4*8)+(3*8)+(2*4)+(1*1)=197
197 % 10 = 7
So 1443988-41-7 is a valid CAS Registry Number.

C2-arylacylation of 2H-benzothiazoles with methyl arenes via Selectfluor oxidation

Chen, Bo,Kong, Yao-Lei,Liu, Jin-Chuan,Lu, Qi,Sun, Xiao-Tong,Weng, Jian-Quan

, (2021)

An efficient Selectfluor-oxidative protocol was developed for the direct C2-arylacylation of 2H-benzothiazoles via the radical reaction of 2H-benzothiazoles with methyl arenes. Selectfluor can effectively promote the oxidative cross-coupling without an ex

Silver-mediated 2-arylation/alkylation/acylation of benzothiazoles with aldehydes in water

Hua, Min,Wang, Chunqin,Liu, Qixing,Chen, Danyi,Fu, Hao,Zhou, Haifeng

, p. 1226 - 1237 (2018/08/06)

An efficient and environmentally benign method was developed for the facile synthesis of various 2-aryl and 2-alkyl substituted benzothiazoles in moderate to good yields, using a silver-mediated redox condensation of benzothiazoles and aldehydes in water. Furthermore, this method is also applicable to prepare 2-acyl benzothiazoles.
