511549-31-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 511549-31-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,1,5,4 and 9 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 511549-31:
(8*5)+(7*1)+(6*1)+(5*5)+(4*4)+(3*9)+(2*3)+(1*1)=128
128 % 10 = 8
So 511549-31-8 is a valid CAS Registry Number.
