91880-23-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91880-23-8 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, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 91880-23:
(7*9)+(6*1)+(5*8)+(4*8)+(3*0)+(2*2)+(1*3)=148
148 % 10 = 8
So 91880-23-8 is a valid CAS Registry Number.
