94458-98-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 94458-98-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,4,4,5 and 8 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 94458-98:
(7*9)+(6*4)+(5*4)+(4*5)+(3*8)+(2*9)+(1*8)=177
177 % 10 = 7
So 94458-98-7 is a valid CAS Registry Number.

A New Synthesis of Bicycloocta-2,4-diene and Its Cycloaddition Reactions with Dienophiles.
Yin, Tyze-Kuan,Lee, Jon Gun,Borden, Weston Thatcher
, p. 531 - 534 (1985)
Bicycloocta-2,4-diene (4) has been synthesized by a new, nine-step route, starting from 2--1,3-butadiene and acrolein.Diene (4) proved almost as unreactive toward Diels-Alder cycloadditions as the previously studied 7,7-dimethy
