Check Digit Verification of cas no
The CAS Registry Mumber 100046-13-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,0,4 and 6 respectively; the second part has 2 digits, 1 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100046-13:
(8*1)+(7*0)+(6*0)+(5*0)+(4*4)+(3*6)+(2*1)+(1*3)=47
47 % 10 = 7
So 100046-13-7 is a valid CAS Registry Number.
