188107-43-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 188107-43-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,8,8,1,0 and 7 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 188107-43:
(8*1)+(7*8)+(6*8)+(5*1)+(4*0)+(3*7)+(2*4)+(1*3)=149
149 % 10 = 9
So 188107-43-9 is a valid CAS Registry Number.
