Check Digit Verification of cas no
The CAS Registry Mumber 130001-39-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,0,0,0 and 1 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 130001-39:
(8*1)+(7*3)+(6*0)+(5*0)+(4*0)+(3*1)+(2*3)+(1*9)=47
47 % 10 = 7
So 130001-39-7 is a valid CAS Registry Number.
