185421-93-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 185421-93-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,4,2 and 1 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 185421-93:
(8*1)+(7*8)+(6*5)+(5*4)+(4*2)+(3*1)+(2*9)+(1*3)=146
146 % 10 = 6
So 185421-93-6 is a valid CAS Registry Number.
