Check Digit Verification of cas no
The CAS Registry Mumber 2657-89-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,6,5 and 7 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 2657-89:
(6*2)+(5*6)+(4*5)+(3*7)+(2*8)+(1*9)=108
108 % 10 = 8
So 2657-89-8 is a valid CAS Registry Number.
