121896-31-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121896-31-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,8,9 and 6 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 121896-31:
(8*1)+(7*2)+(6*1)+(5*8)+(4*9)+(3*6)+(2*3)+(1*1)=129
129 % 10 = 9
So 121896-31-9 is a valid CAS Registry Number.

INTRAMOLECULAR DIELS-ALDER CYCLOADDITIONS OF SUBSTITUTED FURFURYL E-2-(PHENYLSULFONYL)ACRYLATES
Jung, Michael E.,Truc, Vu Chi
, p. 6059 - 6062 (2007/10/02)
Several substituted furfuryl E-2-(phenylsulfonyl)acrylates have been prepared by direct routes and cyclized in good yield under very mild conditions to give highly oxidized systems of potential use in natural products synthesis.
