Check Digit Verification of cas no
The CAS Registry Mumber 26893-27-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,8,9 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26893-27:
(7*2)+(6*6)+(5*8)+(4*9)+(3*3)+(2*2)+(1*7)=146
146 % 10 = 6
So 26893-27-6 is a valid CAS Registry Number.
