6749-55-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6749-55-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,7,4 and 9 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 6749-55:
(6*6)+(5*7)+(4*4)+(3*9)+(2*5)+(1*5)=129
129 % 10 = 9
So 6749-55-9 is a valid CAS Registry Number.
