Check Digit Verification of cas no
The CAS Registry Mumber 3025-77-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,0,2 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 3025-77:
(6*3)+(5*0)+(4*2)+(3*5)+(2*7)+(1*7)=62
62 % 10 = 2
So 3025-77-2 is a valid CAS Registry Number.
