183202-53-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 183202-53-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,3,2,0 and 2 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 183202-53:
(8*1)+(7*8)+(6*3)+(5*2)+(4*0)+(3*2)+(2*5)+(1*3)=111
111 % 10 = 1
So 183202-53-1 is a valid CAS Registry Number.
