1260400-53-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1260400-53-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,6,0,4,0 and 0 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1260400-53:
(9*1)+(8*2)+(7*6)+(6*0)+(5*4)+(4*0)+(3*0)+(2*5)+(1*3)=100
100 % 10 = 0
So 1260400-53-0 is a valid CAS Registry Number.

experimental part, p. 1550 - 1557 (2011/02/23)
Bromination of ethyl 1-aryl-4-acetyl-5-methyl-1H-pyrazole-3-carboxylates gave ethyl 1-aryl-4-(bromoacetyl)-5-methyl-1H-pyrazol-3-carboxylates which were used to alkylate benzenethiol and heterocyclic thiones at the sulfur atom. Reactions of the resulting
