20434-37-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 20434-37-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,3 and 4 respectively; the second part has 2 digits, 3 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 20434-37:
(7*2)+(6*0)+(5*4)+(4*3)+(3*4)+(2*3)+(1*7)=71
71 % 10 = 1
So 20434-37-1 is a valid CAS Registry Number.

Electrochemical oxidative ring opening of 1-methylcyclobutanol
Kapustina,Sokova,Nikishin
, p. 1246 - 1248 (1996)
The manganese(III) acetate-mediated electrooxidative ring opening of 1-methylcyclobutanol (1) in acetic acid affords pentane-2-one (2) as the major product. The reaction of 1-methylcyclobutanol with Mn(OAc)3-LiCl gives 5-chloropentane-2-one (4).
