Check Digit Verification of cas no
The CAS Registry Mumber 109830-34-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,9,8,3 and 0 respectively; the second part has 2 digits, 3 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 109830-34:
(8*1)+(7*0)+(6*9)+(5*8)+(4*3)+(3*0)+(2*3)+(1*4)=124
124 % 10 = 4
So 109830-34-4 is a valid CAS Registry Number.
