Check Digit Verification of cas no
The CAS Registry Mumber 279248-28-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,7,9,2,4 and 8 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 279248-28:
(8*2)+(7*7)+(6*9)+(5*2)+(4*4)+(3*8)+(2*2)+(1*8)=181
181 % 10 = 1
So 279248-28-1 is a valid CAS Registry Number.
