185422-93-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 185422-93-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,5,4,2 and 2 respectively; the second part has 2 digits, 9 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 185422-93:
(8*1)+(7*8)+(6*5)+(5*4)+(4*2)+(3*2)+(2*9)+(1*3)=149
149 % 10 = 9
So 185422-93-9 is a valid CAS Registry Number.
