Check Digit Verification of cas no
The CAS Registry Mumber 261903-03-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,6,1,9,0 and 3 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 261903-03:
(8*2)+(7*6)+(6*1)+(5*9)+(4*0)+(3*3)+(2*0)+(1*3)=121
121 % 10 = 1
So 261903-03-1 is a valid CAS Registry Number.
