Check Digit Verification of cas no

The CAS Registry Mumber 200635-82-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,0,6,3 and 5 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 200635-82:
(8*2)+(7*0)+(6*0)+(5*6)+(4*3)+(3*5)+(2*8)+(1*2)=91
91 % 10 = 1
So 200635-82-1 is a valid CAS Registry Number.

Preparation of 2-(3-Hydroxyalkylthio)benzoxazoles and their Conversion into Thietanes

Ikemizu, Dai,Matsuyama, Ayako,Takemura, Kazunori,Mitsunobu, Oyo

, p. 1247 - 1248 (2007/10/03)

Reaction of primary or secondary 1,3-diols with dibenzoxazol-2-yl disulfide and tributylphosphine or triphenylphosphine selectively gave 2-(3-hydroxyalkylthio)benzoxazoles which, on treatment with KH, were converted into the corresponding thietanes. 2,2-Dibenzylthietane-1-oxide reacted with silylated purines and pyrimidines in the presence of TMSOTf and ZnI2 to give the corresponding thietane nucleosides in 17-69% yields.
