The CAS Registry Mumber 153897-21-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,3,8,9 and 7 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 153897-21:
(8*1)+(7*5)+(6*3)+(5*8)+(4*9)+(3*7)+(2*2)+(1*1)=163
163 % 10 = 3
So 153897-21-3 is a valid CAS Registry Number.
