Check Digit Verification of cas no
The CAS Registry Mumber 891027-95-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,9,1,0,2 and 7 respectively; the second part has 2 digits, 9 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 891027-95:
(8*8)+(7*9)+(6*1)+(5*0)+(4*2)+(3*7)+(2*9)+(1*5)=185
185 % 10 = 5
So 891027-95-5 is a valid CAS Registry Number.
