Check Digit Verification of cas no

The CAS Registry Mumber 24469-13-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,6 and 9 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 24469-13:
(7*2)+(6*4)+(5*4)+(4*6)+(3*9)+(2*1)+(1*3)=114
114 % 10 = 4
So 24469-13-4 is a valid CAS Registry Number.

Pd-Catalyzed Alkenyl Thioether Synthesis from Thioesters and N-Tosylhydrazones

Ishitobi, Kota,Muto, Kei,Yamaguchi, Junichiro

, p. 11685 - 11690 (2019/12/02)

A Pd-catalyzed alkenyl thioether synthesis was achieved using thioesters and N-tosylhydrazones as starting materials. The thioester acted as an efficient "sulfur source" for catalytic C-S bond formation using N-tosylhydrazone. This method gave Z-alkenyl thioethers with high diastereoselectivity (up to 99:1 diastereomeric ratio). This transformation displayed a wide functional group tolerance and was successfully applied to the late-stage derivatization of a pharmaceutical molecule to the corresponding alkenyl thioether.
