Check Digit Verification of cas no

The CAS Registry Mumber 40095-35-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,0,9 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 40095-35:
(7*4)+(6*0)+(5*0)+(4*9)+(3*5)+(2*3)+(1*5)=90
90 % 10 = 0
So 40095-35-0 is a valid CAS Registry Number.

Electrochemical Oxidation, VII. Synthesis and Structure of 7-tert-Butyl-2-methylbenzoxazoles

Dreher, Eberhard-Ludwig,Bracht, Juergen,El-Mobayed, Medhat,Huetter, Peter,Winter, Werner,Rieker, Anton

, p. 288 - 308 (2007/10/02)

Anodic oxidation of 15 tert-butylphenols 1a - o in absolute acetonitrile or acetonitrile/perchloric acid leads to the corresponding 7-tert-butyl-2-methylbenzoxazoles 3a - o.The proof of the structure was achieved by independent synthesis of 3k, and by 13C NMR spectroscopy as well as by X-ray analysis of 7-tert-butyl-2-methyl-5-benzoxazolecarbaldehyde (3j).The influence of the supporting electrolyte on the formation of the oxidation products is discussed.
