Check Digit Verification of cas no
The CAS Registry Mumber 54921-72-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,4,9,2 and 1 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 54921-72:
(7*5)+(6*4)+(5*9)+(4*2)+(3*1)+(2*7)+(1*2)=131
131 % 10 = 1
So 54921-72-1 is a valid CAS Registry Number.
