Check Digit Verification of cas no
The CAS Registry Mumber 209991-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,9,9,9 and 1 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 209991-63:
(8*2)+(7*0)+(6*9)+(5*9)+(4*9)+(3*1)+(2*6)+(1*3)=169
169 % 10 = 9
So 209991-63-9 is a valid CAS Registry Number.

A new Knoevenagel-type synthesis of fully substituted γ- hydroxybutenolides

The synthesis of fully substituted γ-hydroxybutenolides is possible by a Knoevenagel-type ring condensation of α-methyleneketones and α-ketoesters under basic conditions. This novel transformation allowed the preparation of di-aryl/heteroaryl substituted hydroxyfuranones, such as 20 and 27, which are important intermediates for pyridazine fungicides. As it turned out, a whole range of different substituents, such as alkyl, cycloalkyl, aryl, heteroaryl and ester groups could be linked to the butenolide scaffold, demonstrating the broad scope of the novel cyclization.
