Check Digit Verification of cas no
The CAS Registry Mumber 8003-88-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 8,0,0 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 8003-88:
(6*8)+(5*0)+(4*0)+(3*3)+(2*8)+(1*8)=81
81 % 10 = 1
So 8003-88-1 is a valid CAS Registry Number.
