887502-78-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 887502-78-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,8,7,5,0 and 2 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 887502-78:
(8*8)+(7*8)+(6*7)+(5*5)+(4*0)+(3*2)+(2*7)+(1*8)=215
215 % 10 = 5
So 887502-78-5 is a valid CAS Registry Number.
