Check Digit Verification of cas no
The CAS Registry Mumber 2863-88-9 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,8,6 and 3 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2863-88:
(6*2)+(5*8)+(4*6)+(3*3)+(2*8)+(1*8)=109
109 % 10 = 9
So 2863-88-9 is a valid CAS Registry Number.
