Check Digit Verification of cas no
The CAS Registry Mumber 126965-19-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,6,9,6 and 5 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 126965-19:
(8*1)+(7*2)+(6*6)+(5*9)+(4*6)+(3*5)+(2*1)+(1*9)=153
153 % 10 = 3
So 126965-19-3 is a valid CAS Registry Number.
