137944-12-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 137944-12-8 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, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 137944-12:
(8*1)+(7*3)+(6*7)+(5*9)+(4*4)+(3*4)+(2*1)+(1*2)=148
148 % 10 = 8
So 137944-12-8 is a valid CAS Registry Number.
