Check Digit Verification of cas no
The CAS Registry Mumber 137944-39-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,7,9,4 and 4 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 137944-39:
(8*1)+(7*3)+(6*7)+(5*9)+(4*4)+(3*4)+(2*3)+(1*9)=159
159 % 10 = 9
So 137944-39-9 is a valid CAS Registry Number.
