887502-74-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 887502-74-1 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 4 respectively.
Calculate Digit Verification of CAS Registry Number 887502-74:
(8*8)+(7*8)+(6*7)+(5*5)+(4*0)+(3*2)+(2*7)+(1*4)=211
211 % 10 = 1
So 887502-74-1 is a valid CAS Registry Number.
