84702-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 84702-87-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,7,0 and 2 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 84702-87:
(7*8)+(6*4)+(5*7)+(4*0)+(3*2)+(2*8)+(1*7)=144
144 % 10 = 4
So 84702-87-4 is a valid CAS Registry Number.

Two Methoxycarbonylketen Equivalents as Dienophiles in the Diels-Alder Reaction
Gupta, Indranil,Yates, Peter
, p. 1227 - 1228 (2007/10/02)
Methyl methoxypropiolate and methyl (phenylthio)propiolate give Diels-Alder adducts with 1,3-dienes; the adducts with cyclopentadienes give methyl 3-oxobicyclohept-5-ene-2-carboxylates on hydrolysis.
