59908-57-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59908-57-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,9,0 and 8 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 59908-57:
(7*5)+(6*9)+(5*9)+(4*0)+(3*8)+(2*5)+(1*7)=175
175 % 10 = 5
So 59908-57-5 is a valid CAS Registry Number.
