630096-42-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 630096-42-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,3,0,0,9 and 6 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 630096-42:
(8*6)+(7*3)+(6*0)+(5*0)+(4*9)+(3*6)+(2*4)+(1*2)=133
133 % 10 = 3
So 630096-42-3 is a valid CAS Registry Number.

Photoactivated Tungsten Hexacarbonyl-Catalyzed Conversion of Alkynols to Glycals
Wipf, Peter,Graham, Thomas H.
, p. 8798 - 8807 (2007/10/03)
The photoactivated W(CO)6/DABCO/THF system has been used for the formal endo-cyclization of alkynes to pyran rings. We found that the regioselectivity of ring closure depends on the relative configuration of the 3,5-dihydroxy-1-alkynes, as well
