Check Digit Verification of cas no
The CAS Registry Mumber 5203-85-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,0 and 3 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 5203-85:
(6*5)+(5*2)+(4*0)+(3*3)+(2*8)+(1*5)=70
70 % 10 = 0
So 5203-85-0 is a valid CAS Registry Number.

REVERSE MUMM REARRANGEMENTS. I. THERMOLYSIS OF 3-ACETOXY-1-FORMYLINDAZOLE
Dumitrascu, Florea,Raileanu, Dan
, p. 1247 - 1258 (2007/10/03)
2-Acetyl-3-indazolone (15), 1,2-diacetyl-3-indazolone (16) and 3-acetoxy-1-acetylindazole (3) are intermediates of the title thermolysis which leads to 1-acetyl-3-indazolone (4). The rearrangement of 16 to 3 is a reverse Mumm rearrangement which has not yet been observed. The same pattern applies to the acetylation of the 3-indazolone (2). Acylotropic equilibria have been observed between 2-acetyl-1-methyl-3-indazolone (24) and 3-acetoxy-1-methylindazole (26).
