Check Digit Verification of cas no
The CAS Registry Mumber 6375-55-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,7 and 5 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6375-55:
(6*6)+(5*3)+(4*7)+(3*5)+(2*5)+(1*5)=109
109 % 10 = 9
So 6375-55-9 is a valid CAS Registry Number.
