112920-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112920-17-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,9,2 and 0 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 112920-17:
(8*1)+(7*1)+(6*2)+(5*9)+(4*2)+(3*0)+(2*1)+(1*7)=89
89 % 10 = 9
So 112920-17-9 is a valid CAS Registry Number.

Synthesis of (+/-)-Sydonic Acid
Murali, D.,Rao, G. S. Krishna
, p. 156 - 157 (2007/10/02)
A two-step synthesis of sydonic acid (1) makes use of the phenolic acetylbenzoic acid (4) obtained by the regio-selective oxidation of the known 2-acetoxy-4-methylacetophenone (3) by benzyltriethylammonium permanganate (BTAP).Similar BTAP oxidation of the
