139488-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139488-50-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,4,8 and 8 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 139488-50:
(8*1)+(7*3)+(6*9)+(5*4)+(4*8)+(3*8)+(2*5)+(1*0)=169
169 % 10 = 9
So 139488-50-9 is a valid CAS Registry Number.
