1581884-54-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1581884-54-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,5,8,1,8,8 and 4 respectively; the second part has 2 digits, 5 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1581884-54:
(9*1)+(8*5)+(7*8)+(6*1)+(5*8)+(4*8)+(3*4)+(2*5)+(1*4)=209
209 % 10 = 9
So 1581884-54-9 is a valid CAS Registry Number.
