Check Digit Verification of cas no
The CAS Registry Mumber 149021-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,9,0,2 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 149021-03:
(8*1)+(7*4)+(6*9)+(5*0)+(4*2)+(3*1)+(2*0)+(1*3)=104
104 % 10 = 4
So 149021-03-4 is a valid CAS Registry Number.
