Check Digit Verification of cas no
The CAS Registry Mumber 134940-69-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,4,9,4 and 0 respectively; the second part has 2 digits, 6 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 134940-69:
(8*1)+(7*3)+(6*4)+(5*9)+(4*4)+(3*0)+(2*6)+(1*9)=135
135 % 10 = 5
So 134940-69-5 is a valid CAS Registry Number.
