55881-68-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 55881-68-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,5,8,8 and 1 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 55881-68:
(7*5)+(6*5)+(5*8)+(4*8)+(3*1)+(2*6)+(1*8)=160
160 % 10 = 0
So 55881-68-0 is a valid CAS Registry Number.

Phosphonitrilic chloride as an efficient reagent for the synthesis of β-sultams
Zarei, Maaroof
, p. 1100 - 1102 (2013)
A novel and efficient route for the conversion of imines and sulfonic acids into β-sultams using phosphonitrilic chloride at room temperature in dry CH2Cl2 is described. Optimization of the conditions was performed. This method is ve
