Check Digit Verification of cas no

The CAS Registry Mumber 54150-76-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,1,5 and 0 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 54150-76:
(7*5)+(6*4)+(5*1)+(4*5)+(3*0)+(2*7)+(1*6)=104
104 % 10 = 4
So 54150-76-4 is a valid CAS Registry Number.

Synthesis and reactivity of dimethoxy activated benzothiazoles

Alamgir, Mahiuddin,Bhadbhade, Mohan,Black, David StC.,Jiang, Hao,Kumar, Naresh

, p. 1859 - 1882 (2020/11/19)

A range of 2-substituted-5,7-dimethoxybenzothiazoles and 2-substituted-4,6-dimethoxybenzothiazoles have been synthesized by oxidative cyclization of the corresponding thioamides. These activated benzothiazoles display nucleophilic reactivity at C4 and C7 respectively and undergo formylation, acetylation and related reactions. Some 5,7-dimethoxybenzothiazoles with functionalization in a 2-aryl substituent are also reported as potential precursors for so far unsuccessful formation of macrocycles containing two benzothiazoles and two benzimidazoles.
