85579-89-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 85579-89-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,5,7 and 9 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 85579-89:
(7*8)+(6*5)+(5*5)+(4*7)+(3*9)+(2*8)+(1*9)=191
191 % 10 = 1
So 85579-89-1 is a valid CAS Registry Number.
