Check Digit Verification of cas no
The CAS Registry Mumber 65819-26-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,5,8,1 and 9 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 65819-26:
(7*6)+(6*5)+(5*8)+(4*1)+(3*9)+(2*2)+(1*6)=153
153 % 10 = 3
So 65819-26-3 is a valid CAS Registry Number.
