Check Digit Verification of cas no

The CAS Registry Mumber 1021700-66-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,7,0 and 0 respectively; the second part has 2 digits, 6 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 1021700-66:
(9*1)+(8*0)+(7*2)+(6*1)+(5*7)+(4*0)+(3*0)+(2*6)+(1*6)=82
82 % 10 = 2
So 1021700-66-2 is a valid CAS Registry Number.

Synthetic studies on maitotoxin. 2. Stereoselective synthesis of the WXYZA -ring system

Morita, Masayuki,Haketa, Tasuku,Koshino, Hiroyuki,Nakata, Tadashi

supporting information; experimental part, p. 1679 - 1682 (2009/04/12)

The stereoselective synthesis of the WXYZA -ring system of maitotoxin has been accomplished via a linear synthetic approach, in which key reactions were Sml2-induced cyclization of ss-alkoxyacrylate for the construction of the A -, Y-, and X-rings and 6-endo cyclization of hydroxy vinylepoxide for that of the Z- and W-rings.
