The CAS Registry Mumber 1159-87-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,5 and 9 respectively; the second part has 2 digits, 8 and 7 respectively. Calculate Digit Verification of CAS Registry Number 1159-87: (6*1)+(5*1)+(4*5)+(3*9)+(2*8)+(1*7)=81 81 % 10 = 1 So 1159-87-1 is a valid CAS Registry Number.
