Check Digit Verification of cas no
The CAS Registry Mumber 1103-38-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,0 and 3 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1103-38:
(6*1)+(5*1)+(4*0)+(3*3)+(2*3)+(1*8)=34
34 % 10 = 4
So 1103-38-4 is a valid CAS Registry Number.
