Check Digit Verification of cas no
The CAS Registry Mumber 40769-69-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,7,6 and 9 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 40769-69:
(7*4)+(6*0)+(5*7)+(4*6)+(3*9)+(2*6)+(1*9)=135
135 % 10 = 5
So 40769-69-5 is a valid CAS Registry Number.
