72649-02-6 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 72649-02-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,6,4 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72649-02:
(7*7)+(6*2)+(5*6)+(4*4)+(3*9)+(2*0)+(1*2)=136
136 % 10 = 6
So 72649-02-6 is a valid CAS Registry Number.

A concise synthesis of (S)-(+)-5,6-2H-pyran-2-one via hydrozirconation- carbonylation-demetallation of O-benzyl (S)-(-)-4-pentyn-2-ol

Dupont, Jairton,Donato, Augusto J.

, p. 949 - 954 (1998)

A simple synthetic approach to α,β-unsaturated δ-lactones has been devised from the hydrozirconation of O-protected homopropargyl alcohols followed by carbonylation and quenching with iodine. The synthesis of (S)- (+)-5,6-2H-pyran-2-one (parasorbic acid)
