337533-94-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 337533-94-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,3,7,5,3 and 3 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 337533-94:
(8*3)+(7*3)+(6*7)+(5*5)+(4*3)+(3*3)+(2*9)+(1*4)=155
155 % 10 = 5
So 337533-94-5 is a valid CAS Registry Number.

Novel application of the palladium-catalyzed N-arylation of hydrazones to a versatile new synthesis of pyrazoles
Haddad, Nizar,Baron, James
, p. 2171 - 2173 (2002)
A versatile synthesis of pyrazoles from aryl benzophenone hydrazones was demonstrated with a variety of 1,3-bifunctional substrates under acidic conditions. The obtained regioselectivity is consistent with transhydrazonation followed by subsequent cycliza
