188031-28-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188031-28-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,0,3 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 188031-28:
(8*1)+(7*8)+(6*8)+(5*0)+(4*3)+(3*1)+(2*2)+(1*8)=139
139 % 10 = 9
So 188031-28-9 is a valid CAS Registry Number.
