98876-73-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 98876-73-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,8,8,7 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 98876-73:
(7*9)+(6*8)+(5*8)+(4*7)+(3*6)+(2*7)+(1*3)=214
214 % 10 = 4
So 98876-73-4 is a valid CAS Registry Number.
