111680-59-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111680-59-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,8 and 0 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 111680-59:
(8*1)+(7*1)+(6*1)+(5*6)+(4*8)+(3*0)+(2*5)+(1*9)=102
102 % 10 = 2
So 111680-59-2 is a valid CAS Registry Number.
