Check Digit Verification of cas no

The CAS Registry Mumber 157794-07-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,7,7,9 and 4 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 157794-07:
(8*1)+(7*5)+(6*7)+(5*7)+(4*9)+(3*4)+(2*0)+(1*7)=175
175 % 10 = 5
So 157794-07-5 is a valid CAS Registry Number.

Synthesis and Stereochemical Confirmation of the cis-Fused L/M and N/O Ring Systems of Maitotoxin

Sasaki, Makoto,Nonomura, Taro,Murata, Michio,Tachibana, Kazuo

, p. 5023 - 5026 (2007/10/02)

Stereocontrolled synthesis of cis-fused 1,6-dioxadecalin system 1, which corresponds to the L/M and N/O rings of maitotoxin, was accomplished.Comparison of its (1)H and (13)C NMR data with those of the natural toxin established the earlier stereochemical
