Check Digit Verification of cas no

The CAS Registry Mumber 124760-17-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,4,7,6 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 124760-17:
(8*1)+(7*2)+(6*4)+(5*7)+(4*6)+(3*0)+(2*1)+(1*7)=114
114 % 10 = 4
So 124760-17-4 is a valid CAS Registry Number.

Identification and characterization of pectenotoxin (PTX) 4 and PTX7 as spiroketal stereoisomers of two previously reported pectenotoxins

Sasaki,Sasaki, Katsunori,Wright,Wright, Jeffrey L. C.,Yasumoto,Yasumoto, Takeshi

, p. 2475 - 2480 (1998)

Pectenotoxins (PTXs) isolated from the scallon Patinopecten yessoensis were shown to be involved in an episode of diarrhetic shellfish poisoning (DSP). A total of eight analogues (PTX1-PTX7 and PTX10) have been isolated to date, and the structures of four of these analogues (PTX1, PTX2, PTX3, and PTX6) have already been elucidated. Here, we report the characterization of PTX4 and PTX7 as 7-epi-PTX1 and 7-epi-PTX6, respectively, on the basis of NMR data and an acid-catalyzed chemical interconversion. The structures of two new artifacts, PTX8 and PTX9, produced following this treatment are also reported.
