Check Digit Verification of cas no
The CAS Registry Mumber 26978-65-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,9,7 and 8 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 26978-65:
(7*2)+(6*6)+(5*9)+(4*7)+(3*8)+(2*6)+(1*5)=164
164 % 10 = 4
So 26978-65-4 is a valid CAS Registry Number.
