91034-94-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91034-94-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,3 and 4 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 91034-94:
(7*9)+(6*1)+(5*0)+(4*3)+(3*4)+(2*9)+(1*4)=115
115 % 10 = 5
So 91034-94-5 is a valid CAS Registry Number.

SYNTHESIS OF 4-VALEROLACTONE AND 4-BROMOVALERIC ACID.

Slavinskaya,Brezhnev,Sile,Kreile,Eglite,Tomsons,Liepin'sh,Karakhanov

, p. 348 - 352 (2007/10/02)

4-Valerolactone has been obtained by the liquid-phase oxidation of 2,3-dihydropyran with pyridinium chlorochromate. The yields of 4-valerolactone at the liquid-phase oxidation stage reach 90-96% at 90% conversion of the starting material. The isolation of 4-valerolactone is complicated by resinification and condensation. Yields of up to 54% of valerolactone were obtained. 4-Bromovaleric acid was obtained by hydrobrominating 4-valerolactone in dioxane solution, yields of up to 64% of 4-bromovaleric acid being obtained. A by-product of the reaction was beta -( beta prime -bromoethoxy)ethyl 4-bromovalerate.
