Check Digit Verification of cas no
The CAS Registry Mumber 26878-35-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,7 and 8 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26878-35:
(7*2)+(6*6)+(5*8)+(4*7)+(3*8)+(2*3)+(1*5)=153
153 % 10 = 3
So 26878-35-3 is a valid CAS Registry Number.
