Check Digit Verification of cas no
The CAS Registry Mumber 21636-09-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,6,3 and 6 respectively; the second part has 2 digits, 0 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 21636-09:
(7*2)+(6*1)+(5*6)+(4*3)+(3*6)+(2*0)+(1*9)=89
89 % 10 = 9
So 21636-09-9 is a valid CAS Registry Number.
