Check Digit Verification of cas no

The CAS Registry Mumber 63802-23-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,3,8,0 and 2 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 63802-23:
(7*6)+(6*3)+(5*8)+(4*0)+(3*2)+(2*2)+(1*3)=113
113 % 10 = 3
So 63802-23-3 is a valid CAS Registry Number.

Air-Tolerant Direct Thiol Esterification with Carboxylic Acids Using Hydrosilane via Simple Inorganic Base Catalysis

Xuan, Maojie,Lu, Chunlei,Liu, Meina,Lin, Bo-Lin

, p. 7694 - 7701 (2019)

Direct thioesterification of carboxylic acids with thiols using nontoxic activation agents is highly desirable. Herein, an efficient and practical protocol using safe and inexpensive industrial waste polymethylhydrosiloxane as the activation agent and K3PO4 with 18-crown-6 as a catalyst is described. Various functional groups on carboxylic acid and thiol substituents can be tolerated by the present system to afford thioesters in yields of 19-100%.
