Check Digit Verification of cas no
The CAS Registry Mumber 111456-08-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,4,5 and 6 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 111456-08:
(8*1)+(7*1)+(6*1)+(5*4)+(4*5)+(3*6)+(2*0)+(1*8)=87
87 % 10 = 7
So 111456-08-7 is a valid CAS Registry Number.
