Check Digit Verification of cas no

The CAS Registry Mumber 139641-16-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,4 and 1 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 139641-16:
(8*1)+(7*3)+(6*9)+(5*6)+(4*4)+(3*1)+(2*1)+(1*6)=140
140 % 10 = 0
So 139641-16-0 is a valid CAS Registry Number.

The Stereochemical Investigation of 3-Aryl-.4-methyl-1,2,3-oxathiazolidine 2-oxides Using NMR

Nishiyama, Tomihiro,Takahama, Yasumitsu,Yamada, Fukiko

, p. 195 - 197 (2007/10/02)

The title compounds were prepared by the reaction of the corresponding N-2-hydroxyisopropylanilines with thionyl chloride in the presence of triethylamine, and their pmr and cmr spectra were examined.On the basis of the chemical shifts due to the γ and δ-effects, the stereochemical structures are discussed.
