98540-65-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98540-65-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,5,4 and 0 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 98540-65:
(7*9)+(6*8)+(5*5)+(4*4)+(3*0)+(2*6)+(1*5)=169
169 % 10 = 9
So 98540-65-9 is a valid CAS Registry Number.
