Check Digit Verification of cas no
The CAS Registry Mumber 7464-75-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,4,6 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 7464-75:
(6*7)+(5*4)+(4*6)+(3*4)+(2*7)+(1*5)=117
117 % 10 = 7
So 7464-75-7 is a valid CAS Registry Number.
