Check Digit Verification of cas no
The CAS Registry Mumber 2657-67-2 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, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2657-67:
(6*2)+(5*6)+(4*5)+(3*7)+(2*6)+(1*7)=102
102 % 10 = 2
So 2657-67-2 is a valid CAS Registry Number.
