516458-20-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 516458-20-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,6,4,5 and 8 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 516458-20:
(8*5)+(7*1)+(6*6)+(5*4)+(4*5)+(3*8)+(2*2)+(1*0)=151
151 % 10 = 1
So 516458-20-1 is a valid CAS Registry Number.
