81505-60-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 81505-60-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,5,0 and 5 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81505-60:
(7*8)+(6*1)+(5*5)+(4*0)+(3*5)+(2*6)+(1*0)=114
114 % 10 = 4
So 81505-60-4 is a valid CAS Registry Number.
