Check Digit Verification of cas no
The CAS Registry Mumber 72559-77-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,5,5 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 72559-77:
(7*7)+(6*2)+(5*5)+(4*5)+(3*9)+(2*7)+(1*7)=154
154 % 10 = 4
So 72559-77-4 is a valid CAS Registry Number.
