Check Digit Verification of cas no
The CAS Registry Mumber 1543-55-1 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 3 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1543-55:
(6*1)+(5*5)+(4*4)+(3*3)+(2*5)+(1*5)=71
71 % 10 = 1
So 1543-55-1 is a valid CAS Registry Number.
