98711-80-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98711-80-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,7,1 and 1 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98711-80:
(7*9)+(6*8)+(5*7)+(4*1)+(3*1)+(2*8)+(1*0)=169
169 % 10 = 9
So 98711-80-9 is a valid CAS Registry Number.
