Check Digit Verification of cas no

The CAS Registry Mumber 137487-76-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,4,8 and 7 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 137487-76:
(8*1)+(7*3)+(6*7)+(5*4)+(4*8)+(3*7)+(2*7)+(1*6)=164
164 % 10 = 4
So 137487-76-4 is a valid CAS Registry Number.

The Stereochemical Investigation of 8-Membered 1,3,6-Dioxazocines via NMR

Nishiyama, Tomihiro,Iwasaki, Yoshiaki,Nishikawa, Takeshi,Miyatake, Shinji,Yamada, Fukiko

, p. 1369 - 1372 (2007/10/02)

The stereochemical properties of 2-,4-,7-, and 8-methyl substituted 5,6,7,8-tetrahydro-1,3,6-dioxazocines have been investigated by their pmr and cmr spectroscopy.On the basis of the coupling constants and γ-effects, the stereochemical structures are discussed.
