1427-12-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1427-12-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,4,2 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1427-12:
(6*1)+(5*4)+(4*2)+(3*7)+(2*1)+(1*2)=59
59 % 10 = 9
So 1427-12-9 is a valid CAS Registry Number.
