Check Digit Verification of cas no

The CAS Registry Mumber 58973-25-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,9,7 and 3 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 58973-25:
(7*5)+(6*8)+(5*9)+(4*7)+(3*3)+(2*2)+(1*5)=174
174 % 10 = 4
So 58973-25-4 is a valid CAS Registry Number.

Visible-Light-Mediated C(sp3)–H Thiocarbonylation for Thiolactam Preparation with Potassium Sulfide

Tan, Wei,Wang, Cuihong,Jiang, Xuefeng

, p. 1234 - 1238 (2019/11/21)

We report herein a protocol for thiolactam preparation with potassium sulfide via visible-light-mediated C(sp3)–H thiocarbonylation, in which polysulfide dianions and radical anions generated from potassium sulfide were the key active species. A variety of thiolactams were straightforward established under mild conditions. Moreover, it was successfully applied to structural modification of tetrahydroberberine.
