501668-16-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 501668-16-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,0,1,6,6 and 8 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 501668-16:
(8*5)+(7*0)+(6*1)+(5*6)+(4*6)+(3*8)+(2*1)+(1*6)=132
132 % 10 = 2
So 501668-16-2 is a valid CAS Registry Number.

Extension of ring closing metathesis methodology to the synthesis of carbocyclic methyl and silyl enol ethers
Aggarwal, Varinder K.,Daly, Adrian M.
, p. 2490 - 2491 (2007/10/03)
Carbocyclic methyland silylenol ethers (TBDMS is optimum) can be synthesised regiospecifically by ring closing metathesis using the 'second generation' Grubbs ruthenium carbene catalyst incombination with molecular sieves.
