Check Digit Verification of cas no

The CAS Registry Mumber 14210-70-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,2,1 and 0 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 14210-70:
(7*1)+(6*4)+(5*2)+(4*1)+(3*0)+(2*7)+(1*0)=59
59 % 10 = 9
So 14210-70-9 is a valid CAS Registry Number.

Water-Soluble Acylating Agents: Preparation of 2-Acylthio-1-alkylpyridinium Salts and Acylation of Phenols, Acids, and/or Amines with These Salts in an Aqueous Phase

Sakakibara, Tohru,Watabe, Yukie,Yamada, Masahide,Sudoh, Rokuro

, p. 247 - 254 (2007/10/02)

Reaction of phenols, amines, and acids with 2-benzoylthio-1-methylpyridinium chloride prepared in situ from benzoyl chloride and 1-methyl-2(1H)-pyridinethione, afforded the corresponding benzoyl derivatives in good yields.In the reaction of p-nitrophenol, even catalytic amount of 1-methyl-2(1H)-pyridinethione proved to be effective.Similar reactions of p-nitrophenol with isobutyryl chloride and acetyl chloride in the presence of 1-methyl-2(1H)-pyridinethione afforded p-nitrophenyl isobutyrate and p-nitrophenyl acetate in 63 and 44percent yields, respectively. 2-Benzoylthio-, 2-acetylthio-, and 2-isobutyrylthio-1-ethylpyridinium tetrafluorobora tes were prepared by treatment of the corresponding 2-acylthiopyridines with triethyloxonium tetrafluoroborate.These pyridinium salts also acted as acylating agents in an aqueous phase. some competitive reactions of 2-aminoethanol and phenols with 2-benzoylthio-1-methylpyridinium chloride were also investigated.
