111649-64-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 111649-64-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,1,6,4 and 9 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 111649-64:
(8*1)+(7*1)+(6*1)+(5*6)+(4*4)+(3*9)+(2*6)+(1*4)=110
110 % 10 = 0
So 111649-64-0 is a valid CAS Registry Number.
