Check Digit Verification of cas no
The CAS Registry Mumber 129660-10-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,9,6,6 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 129660-10:
(8*1)+(7*2)+(6*9)+(5*6)+(4*6)+(3*0)+(2*1)+(1*0)=132
132 % 10 = 2
So 129660-10-2 is a valid CAS Registry Number.

The synthesis of some 2H-pyran-2-one derivatives
Kvita,Sauter
, p. 883 - 889 (1990)
Derivatives of 6-unsubstituted 2H-pyran-2-one have been synthesized by several different methods. The 4-chloro-2H-pyran-2-one (9) is the most important, since it serves as starting material for the synthesis of different 4-substituted 2H-pyran-2-ones (Sch
