1004974-55-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1004974-55-3 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,0,4,9,7 and 4 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1004974-55:
(9*1)+(8*0)+(7*0)+(6*4)+(5*9)+(4*7)+(3*4)+(2*5)+(1*5)=133
133 % 10 = 3
So 1004974-55-3 is a valid CAS Registry Number.

Facile access to pyrazolines via domino reaction of the Huisgen zwitterions with aziridines
Cui, Sun-Liang,Wang, Jing,Wang, Yan-Guang
, p. 13 - 16 (2008/09/17)
A novel, efficient, and general domino reaction of 2-acylaziridines with the Huisgen zwitterions to furnish 2-pyrazoline rings is described. A possible mechanism for the domino sequence is proposed.
