91880-16-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91880-16-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,8,8 and 0 respectively; the second part has 2 digits, 1 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91880-16:
(7*9)+(6*1)+(5*8)+(4*8)+(3*0)+(2*1)+(1*6)=149
149 % 10 = 9
So 91880-16-9 is a valid CAS Registry Number.
