The CAS Registry Mumber 77038-40-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,0,3 and 8 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 77038-40:
(7*7)+(6*7)+(5*0)+(4*3)+(3*8)+(2*4)+(1*0)=135
135 % 10 = 5
So 77038-40-5 is a valid CAS Registry Number.
