7Check Digit Verification of cas no
The CAS Registry Mumber 51053-43-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,1,0,5 and 3 respectively; the second part has 2 digits, 4 and 3 respectively.Calculate Digit Verification of CAS Registry Number 51053-43:
(7*5)+(6*1)+(5*0)+(4*5)+(3*3)+(2*4)+(1*3)=81
81 % 10 = 1
So 51053-43-1 is a valid CAS Registry Number.
