91880-15-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 91880-15-8 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, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 91880-15:
(7*9)+(6*1)+(5*8)+(4*8)+(3*0)+(2*1)+(1*5)=148
148 % 10 = 8
So 91880-15-8 is a valid CAS Registry Number.
