659725-89-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 659725-89-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,9,7,2 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 659725-89:
(8*6)+(7*5)+(6*9)+(5*7)+(4*2)+(3*5)+(2*8)+(1*9)=220
220 % 10 = 0
So 659725-89-0 is a valid CAS Registry Number.
