91898-10-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91898-10-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,9 and 8 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 91898-10:
(7*9)+(6*1)+(5*8)+(4*9)+(3*8)+(2*1)+(1*0)=171
171 % 10 = 1
So 91898-10-1 is a valid CAS Registry Number.
