Check Digit Verification of cas no

The CAS Registry Mumber 113503-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,3,5,0 and 3 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 113503-02:
(8*1)+(7*1)+(6*3)+(5*5)+(4*0)+(3*3)+(2*0)+(1*2)=69
69 % 10 = 9
So 113503-02-9 is a valid CAS Registry Number.

Functionalized 3(2H)-furanones via photooxygenation of (β-keto)-2- substituted furans: Application to the biomimetic synthesis of merrekentrone C

Gryparis, Charis,Lykakis, Ioannis N.,Efe, Christina,Zaravinos, Ioannis-Panayotis,Vidali, Theonymphi,Kladou, Eugenia,Stratakis, Manolis

, p. 5655 - 5658 (2011/09/16)

Photooxygenation of (β-keto)-2-substituted furans leads, in a one pot operation, to functionalized 3(2H)-furanones with good to excellent yields. This methodology was applied as a key-step to the concise and biomimetic synthesis of the sesquiterpene merre

A NEW CONVENIENT SYNTHESIS OF 3(2H)-FURANONES

Antonioletti, R.,Bonadies, F.,Scettri, A.

, p. 2297 - 2298 (2007/10/02)

A selective oxidative fission of the heterocyclic nucleus of 5-methyl-2-(acylmethyl)furans or 2-(5-methyl-2-furyl)-1,3-dicarbonyl compounds by m-chloroperbenzoic acid allows the easy synthesis of the 3(2H)-furanone system.
