139694-44-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139694-44-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,6,9 and 4 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 139694-44:
(8*1)+(7*3)+(6*9)+(5*6)+(4*9)+(3*4)+(2*4)+(1*4)=173
173 % 10 = 3
So 139694-44-3 is a valid CAS Registry Number.
