138328-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 138328-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,3,8,3,2 and 8 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 138328-89:
(8*1)+(7*3)+(6*8)+(5*3)+(4*2)+(3*8)+(2*8)+(1*9)=149
149 % 10 = 9
So 138328-89-9 is a valid CAS Registry Number.
