6638-02-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 6638-02-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,6,3 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 6638-02:
(6*6)+(5*6)+(4*3)+(3*8)+(2*0)+(1*2)=104
104 % 10 = 4
So 6638-02-4 is a valid CAS Registry Number.
