Check Digit Verification of cas no
The CAS Registry Mumber 69151-21-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,1,5 and 1 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 69151-21:
(7*6)+(6*9)+(5*1)+(4*5)+(3*1)+(2*2)+(1*1)=129
129 % 10 = 9
So 69151-21-9 is a valid CAS Registry Number.
