The CAS Registry Mumber 138480-79-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,4,8 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138480-79:
(8*1)+(7*3)+(6*8)+(5*4)+(4*8)+(3*0)+(2*7)+(1*9)=152
152 % 10 = 2
So 138480-79-2 is a valid CAS Registry Number.
