The CAS Registry Mumber 72036-32-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,0,3 and 6 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 72036-32:
(7*7)+(6*2)+(5*0)+(4*3)+(3*6)+(2*3)+(1*2)=99
99 % 10 = 9
