616867-45-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 616867-45-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,1,6,8,6 and 7 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 616867-45:
(8*6)+(7*1)+(6*6)+(5*8)+(4*6)+(3*7)+(2*4)+(1*5)=189
189 % 10 = 9
So 616867-45-9 is a valid CAS Registry Number.
