Check Digit Verification of cas no

The CAS Registry Mumber 1021876-90-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,8,7 and 6 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1021876-90:
(9*1)+(8*0)+(7*2)+(6*1)+(5*8)+(4*7)+(3*6)+(2*9)+(1*0)=133
133 % 10 = 3
So 1021876-90-3 is a valid CAS Registry Number.

Synthetic studies on maitotoxin. 3. Stereoselective synthesis of the BCDE-ring system

Satoh, Masanori,Koshino, Hiroyuki,Nakata, Tadashi

, p. 1683 - 1685 (2008)

The stereoselective synthesis of the BCDE-ring system of maitotoxin has been accomplished through a two-directional strategy for the construction of polycyclic ether. The key reactions involve Sml2-induced double cyclization of a ss-alkoxyacrylate and a double dihydroxylation for construction of the B- and E-rings.
