40753-17-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 40753-17-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,7,5 and 3 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 40753-17:
(7*4)+(6*0)+(5*7)+(4*5)+(3*3)+(2*1)+(1*7)=101
101 % 10 = 1
So 40753-17-1 is a valid CAS Registry Number.

Synthesis of Alkynylthiopyridinium Salts and Their Use as Thioketene Equivalents

Averesch, Kai F. G.,Pesch, Henner,Golz, Christopher,Alcarazo, Manuel

supporting information, p. 10472 - 10477 (2019/07/18)

A synthetic method has been developed for the preparation of dihalo(pyridinium)sulfuranes and their transformation into alkynylthiopyridinium salts, starting from inexpensive thiopyridones. The reactivity of these salts towards different nucleophiles is evaluated. Most thiols and amines are converted into dithioesters and thioamides, respectively; whereas sterically demanding thiols delivered alkynylthioethers. These results, together with preliminary mechanistic studies reveal that alkynylthiopyridinium salts can be considered synthetic equivalents of unstable thioketenes.
