Check Digit Verification of cas no
The CAS Registry Mumber 111085-59-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,0,8 and 5 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111085-59:
(8*1)+(7*1)+(6*1)+(5*0)+(4*8)+(3*5)+(2*5)+(1*9)=87
87 % 10 = 7
So 111085-59-7 is a valid CAS Registry Number.
