Check Digit Verification of cas no

The CAS Registry Mumber 757-20-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,5 and 7 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 757-20:
(5*7)+(4*5)+(3*7)+(2*2)+(1*0)=80
80 % 10 = 0
So 757-20-0 is a valid CAS Registry Number.

REACTION BEHAVIOR OF CARBON-CARBON AND CARBON-HYDROGEN BONDS IN SUPER ACIDS. CARBOXYLATION OF ALKYL METHYL KETONES WITH CARBON MONOXIDE AND WATER

Yoneda, Norihiko,Sato, Haruhiko,Fukuhara, Tsuyoshi,Takahashi, Yukio,Suzuki, Akira

, p. 19 - 20 (2007/10/02)

In a HF-SbF5 solution at -20 -ca.30 deg C under atmospheric pressure, ketones having alkyl groups with five or more carbon atoms underwent the reaction to give corresponding oxo carboxylic acids without any β-scission processes which occur readily in alkyl cations derived by protolysis of alkalnes with seven or more carbon atoms.Tertiary C-H bond located at δ or further away from the oxo group in the substrates could react exclusively to give (ω-1)-oxo-2,2-dimethyl carboxylic acids at -20 deg C.
