Check Digit Verification of cas no
The CAS Registry Mumber 2588-88-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,5,8 and 8 respectively; the second part has 2 digits, 8 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2588-88:
(6*2)+(5*5)+(4*8)+(3*8)+(2*8)+(1*8)=117
117 % 10 = 7
So 2588-88-7 is a valid CAS Registry Number.
