Check Digit Verification of cas no

The CAS Registry Mumber 100540-90-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,5,4 and 0 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 100540-90:
(8*1)+(7*0)+(6*0)+(5*5)+(4*4)+(3*0)+(2*9)+(1*0)=67
67 % 10 = 7
So 100540-90-7 is a valid CAS Registry Number.

Facile syntheses of 3-trifluoromethylthio substituted thioflavones and benzothiophenes via the radical cyclization

Wang, Lu,Wang, Huaiyu,Meng, Weidong,Xu, Xiu-Hua,Huang, Yangen

supporting information, p. 389 - 392 (2020/03/04)

3-CF3S substituted thioflavones and benzothiophenes were achieved via the reactions of AgSCF3 with methylthiolated alkynones and alkynylthioanisoles, respectively, promoted by persulfate. This protocol possesses good functional group tolerance and high yields. Mechanistic studies suggested that a classic two-step radical process was involved, which includes addition of CF3S radical to triple bond and cyclization with SMe moiety.
