The CAS Registry Mumber 72853-89-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,2,8,5 and 3 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 72853-89: (7*7)+(6*2)+(5*8)+(4*5)+(3*3)+(2*8)+(1*9)=155 155 % 10 = 5 So 72853-89-5 is a valid CAS Registry Number.
