2774-78-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 2774-78-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,7,7 and 4 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2774-78:
(6*2)+(5*7)+(4*7)+(3*4)+(2*7)+(1*8)=109
109 % 10 = 9
So 2774-78-9 is a valid CAS Registry Number.
