59807-34-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 59807-34-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,9,8,0 and 7 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 59807-34:
(7*5)+(6*9)+(5*8)+(4*0)+(3*7)+(2*3)+(1*4)=160
160 % 10 = 0
So 59807-34-0 is a valid CAS Registry Number.
