Check Digit Verification of cas no
The CAS Registry Mumber 103038-68-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,3,0,3 and 8 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 103038-68:
(8*1)+(7*0)+(6*3)+(5*0)+(4*3)+(3*8)+(2*6)+(1*8)=82
82 % 10 = 2
So 103038-68-2 is a valid CAS Registry Number.
