Check Digit Verification of cas no
The CAS Registry Mumber 75521-14-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,2 and 1 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 75521-14:
(7*7)+(6*5)+(5*5)+(4*2)+(3*1)+(2*1)+(1*4)=121
121 % 10 = 1
So 75521-14-1 is a valid CAS Registry Number.
