Check Digit Verification of cas no
The CAS Registry Mumber 21597-32-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,5,9 and 7 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 21597-32:
(7*2)+(6*1)+(5*5)+(4*9)+(3*7)+(2*3)+(1*2)=110
110 % 10 = 0
So 21597-32-0 is a valid CAS Registry Number.
