73718-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 73718-41-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,3,7,1 and 8 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 73718-41:
(7*7)+(6*3)+(5*7)+(4*1)+(3*8)+(2*4)+(1*1)=139
139 % 10 = 9
So 73718-41-9 is a valid CAS Registry Number.

ISOMERISM OF HYDRAZONES OF (2-BENZOTHIAZOLYLTHIO)- AND (2-BENZOXAZOLYLTHIO)ACETIC ACIDS
Rutavicius, A.,Valiulene, S.,Kuodis, Z.
, p. 629 - 633 (2007/10/03)
PMR spectroscopy was used to shown that the hydrazones of (2-benzothiazolyl) and (2-benzoxazolyl)acetic acids exist in solution as equilibrium mixtures of stereoisomeric forms due to conformational and geometric isomerism.
