Check Digit Verification of cas no
The CAS Registry Mumber 109277-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,2,7 and 7 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 109277-03:
(8*1)+(7*0)+(6*9)+(5*2)+(4*7)+(3*7)+(2*0)+(1*3)=124
124 % 10 = 4
So 109277-03-4 is a valid CAS Registry Number.
