The CAS Registry Mumber 42528-50-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,2,5,2 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 42528-50:
(7*4)+(6*2)+(5*5)+(4*2)+(3*8)+(2*5)+(1*0)=107
107 % 10 = 7
So 42528-50-7 is a valid CAS Registry Number.
