1544-81-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1544-81-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,5,4 and 4 respectively; the second part has 2 digits, 8 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 1544-81:
(6*1)+(5*5)+(4*4)+(3*4)+(2*8)+(1*1)=76
76 % 10 = 6
So 1544-81-6 is a valid CAS Registry Number.
