139705-50-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139705-50-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,7,0 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139705-50:
(8*1)+(7*3)+(6*9)+(5*7)+(4*0)+(3*5)+(2*5)+(1*0)=143
143 % 10 = 3
So 139705-50-3 is a valid CAS Registry Number.
