139286-23-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 139286-23-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,9,2,8 and 6 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 139286-23:
(8*1)+(7*3)+(6*9)+(5*2)+(4*8)+(3*6)+(2*2)+(1*3)=150
150 % 10 = 0
So 139286-23-0 is a valid CAS Registry Number.
