Check Digit Verification of cas no

The CAS Registry Mumber 172427-41-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,4,2 and 7 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 172427-41:
(8*1)+(7*7)+(6*2)+(5*4)+(4*2)+(3*7)+(2*4)+(1*1)=127
127 % 10 = 7
So 172427-41-7 is a valid CAS Registry Number.

Stereochemical assignment of the C35-C39 acyclic linkage in maitotoxin: Completion of stereochemical determination of C15-C134

Sasaki, Makoto,Matsumori, Nobuaki,Murata, Michio,Tachibana, Kazuo,Yasumoto, Takeshi

, p. 9011 - 9014 (2007/10/02)

The relative configuration of carbons within the C35-C39 acyclic linkage of maitotoxin (MTX) was assigned by synthesis of stereodefined model compound 1 and its comparison with MTX in 1H and 13C NMR spectra. This result completed stereochemical assignments of the whole molecule except for side chains.
