188730-45-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188730-45-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,7,3 and 0 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 188730-45:
(8*1)+(7*8)+(6*8)+(5*7)+(4*3)+(3*0)+(2*4)+(1*5)=172
172 % 10 = 2
So 188730-45-2 is a valid CAS Registry Number.
