185331-28-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 185331-28-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,3,3 and 1 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 185331-28:
(8*1)+(7*8)+(6*5)+(5*3)+(4*3)+(3*1)+(2*2)+(1*8)=136
136 % 10 = 6
So 185331-28-6 is a valid CAS Registry Number.
