98543-50-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98543-50-1 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 3 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 98543-50:
(7*9)+(6*8)+(5*5)+(4*4)+(3*3)+(2*5)+(1*0)=171
171 % 10 = 1
So 98543-50-1 is a valid CAS Registry Number.
