The CAS Registry Mumber 83413-42-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,3,4,1 and 3 respectively; the second part has 2 digits, 4 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 83413-42:
(7*8)+(6*3)+(5*4)+(4*1)+(3*3)+(2*4)+(1*2)=117
117 % 10 = 7
So 83413-42-7 is a valid CAS Registry Number.
