Check Digit Verification of cas no
The CAS Registry Mumber 140636-26-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,0,6,3 and 6 respectively; the second part has 2 digits, 2 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 140636-26:
(8*1)+(7*4)+(6*0)+(5*6)+(4*3)+(3*6)+(2*2)+(1*6)=106
106 % 10 = 6
So 140636-26-6 is a valid CAS Registry Number.
