87668-43-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87668-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,7,6,6 and 8 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 87668-43:
(7*8)+(6*7)+(5*6)+(4*6)+(3*8)+(2*4)+(1*3)=187
187 % 10 = 7
So 87668-43-7 is a valid CAS Registry Number.
