Check Digit Verification of cas no
The CAS Registry Mumber 269060-13-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,9,0,6 and 0 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 269060-13:
(8*2)+(7*6)+(6*9)+(5*0)+(4*6)+(3*0)+(2*1)+(1*3)=141
141 % 10 = 1
So 269060-13-1 is a valid CAS Registry Number.
