Check Digit Verification of cas no
The CAS Registry Mumber 52663-72-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,6,6 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 52663-72:
(7*5)+(6*2)+(5*6)+(4*6)+(3*3)+(2*7)+(1*2)=126
126 % 10 = 6
So 52663-72-6 is a valid CAS Registry Number.
