Check Digit Verification of cas no
The CAS Registry Mumber 84910-98-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,4,9,1 and 0 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 84910-98:
(7*8)+(6*4)+(5*9)+(4*1)+(3*0)+(2*9)+(1*8)=155
155 % 10 = 5
So 84910-98-5 is a valid CAS Registry Number.
