Check Digit Verification of cas no

The CAS Registry Mumber 1234064-73-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,0,6 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1234064-73:
(9*1)+(8*2)+(7*3)+(6*4)+(5*0)+(4*6)+(3*4)+(2*7)+(1*3)=123
123 % 10 = 3
So 1234064-73-3 is a valid CAS Registry Number.

Total synthesis of the proposed structure of iriomoteolide-1a

Xie, Jun,Ma, Yuelong,Horne, David A

supporting information; experimental part, p. 4770 - 4772 (2010/09/05)

The total synthesis of the proposed structure of iriomoteolide-1a has been accomplished via a Yamaguchi esterification and ring closing metathesis sequence between the C(7)-C(23) and newly synthesized Z-alkenoic acid C(1)-C(6) fragments. The spectral data of the synthetic 1, however, is at odds with data reported for the natural product, thus bringing into question the original structural assignment.
