98217-32-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98217-32-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,2,1 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 98217-32:
(7*9)+(6*8)+(5*2)+(4*1)+(3*7)+(2*3)+(1*2)=154
154 % 10 = 4
So 98217-32-4 is a valid CAS Registry Number.
