637024-33-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 637024-33-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,7,0,2 and 4 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 637024-33:
(8*6)+(7*3)+(6*7)+(5*0)+(4*2)+(3*4)+(2*3)+(1*3)=140
140 % 10 = 0
So 637024-33-0 is a valid CAS Registry Number.

Synthesis and Cycloaromatization of a Cyclic Enyne-Allene Prodrug
Bekele, Tefsit,Brunette, Steven R.,Lipton, Mark A.
, p. 8471 - 8479 (2003)
A simple and stable cyclic enediynone (4) has been synthesized using an intramolecular Nozaki-Hiyama-Kishi cyclization as the key step. Reaction with a thiolate nucleophile led to rapid cycloaromatization of 4. Trapping experiments using 1,4-cyclohexadien
