118554-11-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 118554-11-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,8,5,5 and 4 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 118554-11:
(8*1)+(7*1)+(6*8)+(5*5)+(4*5)+(3*4)+(2*1)+(1*1)=123
123 % 10 = 3
So 118554-11-3 is a valid CAS Registry Number.
