1391709-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1391709-89-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,3,9,1,7,0 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1391709-89:
(9*1)+(8*3)+(7*9)+(6*1)+(5*7)+(4*0)+(3*9)+(2*8)+(1*9)=189
189 % 10 = 9
So 1391709-89-9 is a valid CAS Registry Number.
