Check Digit Verification of cas no
The CAS Registry Mumber 915091-77-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,5,0,9 and 1 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 915091-77:
(8*9)+(7*1)+(6*5)+(5*0)+(4*9)+(3*1)+(2*7)+(1*7)=169
169 % 10 = 9
So 915091-77-9 is a valid CAS Registry Number.
