The CAS Registry Mumber 87633-22-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,3 and 3 respectively; the second part has 2 digits, 2 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87633-22:
(7*8)+(6*7)+(5*6)+(4*3)+(3*3)+(2*2)+(1*2)=155
155 % 10 = 5
So 87633-22-5 is a valid CAS Registry Number.
