Check Digit Verification of cas no

The CAS Registry Mumber 156210-85-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,2,1 and 0 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 156210-85:
(8*1)+(7*5)+(6*6)+(5*2)+(4*1)+(3*0)+(2*8)+(1*5)=114
114 % 10 = 4
So 156210-85-4 is a valid CAS Registry Number.

Methylthiolation for Electron-Rich Heteroarenes with DMSO-TsCl

Zhang, Lei-Yang,Wu, Yue-Hua,Wang, Nai-Xing,Gao, Xue-Wang,Yan, Zhan,Xu, Bao-Cai,Liu, Ning,Wang, Bo-Zhou,Xing, Yalan

, p. 1446 - 1451 (2021)

DMSO-TsCl has been developed for direct methylthiolation of various electron-rich heteroarenes (more than 40 examples) with high regioselectivity in moderate to excellent yields (up to 96 %). Especially, pyrroles, furans, and thiophenes can be efficiently mono-methylthiolated. This practical method features scalable, metal-free, mild conditions and is compatible with air and moisture. Several applications of methylthiolated products were demonstrated for the first time. Based on controlled experimental results, a plausible mechanism was proposed with two key intermediates involved in the mechanism being detected by HRMS.
