88187-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 88187-28-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,8,1,8 and 7 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 88187-28:
(7*8)+(6*8)+(5*1)+(4*8)+(3*7)+(2*2)+(1*8)=174
174 % 10 = 4
So 88187-28-4 is a valid CAS Registry Number.
