Check Digit Verification of cas no
The CAS Registry Mumber 1330-38-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,3 and 0 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1330-38:
(6*1)+(5*3)+(4*3)+(3*0)+(2*3)+(1*8)=47
47 % 10 = 7
So 1330-38-7 is a valid CAS Registry Number.
