139439-18-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139439-18-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,3 and 9 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 139439-18:
(8*1)+(7*3)+(6*9)+(5*4)+(4*3)+(3*9)+(2*1)+(1*8)=152
152 % 10 = 2
So 139439-18-2 is a valid CAS Registry Number.
