The CAS Registry Mumber 1020108-59-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,1,0 and 8 respectively; the second part has 2 digits, 5 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1020108-59:
(9*1)+(8*0)+(7*2)+(6*0)+(5*1)+(4*0)+(3*8)+(2*5)+(1*9)=71
71 % 10 = 1
So 1020108-59-1 is a valid CAS Registry Number.
