Check Digit Verification of cas no
The CAS Registry Mumber 240816-34-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,0,8,1 and 6 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 240816-34:
(8*2)+(7*4)+(6*0)+(5*8)+(4*1)+(3*6)+(2*3)+(1*4)=116
116 % 10 = 6
So 240816-34-6 is a valid CAS Registry Number.

, p. 665 - 697 (1999)
A Stille coupling strategy has been utilized to complete a total synthesis of epothilone E from vinyl iodide 7 and thiazole-stannane 8h. The central core fragment 7 and its trans-isomer 11 were prepared from triene 15 using ring-closing metathesis (RCM),
