The CAS Registry Mumber 87936-30-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,9,3 and 6 respectively; the second part has 2 digits, 3 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 87936-30:
(7*8)+(6*7)+(5*9)+(4*3)+(3*6)+(2*3)+(1*0)=179
179 % 10 = 9
So 87936-30-9 is a valid CAS Registry Number.
