1190280-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1190280-78-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,2,8 and 0 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1190280-78:
(9*1)+(8*1)+(7*9)+(6*0)+(5*2)+(4*8)+(3*0)+(2*7)+(1*8)=144
144 % 10 = 4
So 1190280-78-4 is a valid CAS Registry Number.

A convenient and rapid approach for the synthesis of 1-benzyl-3-heterocyclic pyrazoles
Curtis, Michael P.,Sammons, Matthew F.,Piotrowski, David W.
scheme or table, p. 5479 - 5481 (2010/01/11)
A variety of 1-benzyl-3-heterocyclic pyrazoles were rapidly assembled by a two-step N-benzylation/Suzuki coupling sequence. A one-pot variation of this sequence is demonstrated.
