4438-85-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4438-85-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,4,3 and 8 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 4438-85:
(6*4)+(5*4)+(4*3)+(3*8)+(2*8)+(1*5)=101
101 % 10 = 1
So 4438-85-1 is a valid CAS Registry Number.
