443141-74-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 443141-74-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,4,3,1,4 and 1 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 443141-74:
(8*4)+(7*4)+(6*3)+(5*1)+(4*4)+(3*1)+(2*7)+(1*4)=120
120 % 10 = 0
So 443141-74-0 is a valid CAS Registry Number.

Cycloaddition reactions of 3-fluorobutenone
Patrick, Timothy B.,Li, Hongli
body text, p. 544 - 546 (2009/12/05)
3-Fluorobutenone (8) reacted as a dienophile with several dienes 9, 11, 13, 15, 17 to give cycloaddition products in moderate yields. The regio- and stereoselectivity of the reactions are given. Compound 8 is slightly less reactive than methyl vinyl keton
