91057-86-2 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 91057-86-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,1,0,5 and 7 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 91057-86:
(7*9)+(6*1)+(5*0)+(4*5)+(3*7)+(2*8)+(1*6)=132
132 % 10 = 2
So 91057-86-2 is a valid CAS Registry Number.
