87664-51-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 87664-51-5 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 4 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 87664-51:
(7*8)+(6*7)+(5*6)+(4*6)+(3*4)+(2*5)+(1*1)=175
175 % 10 = 5
So 87664-51-5 is a valid CAS Registry Number.
