139209-41-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139209-41-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,0 and 9 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139209-41:
(8*1)+(7*3)+(6*9)+(5*2)+(4*0)+(3*9)+(2*4)+(1*1)=129
129 % 10 = 9
So 139209-41-9 is a valid CAS Registry Number.
