158504-45-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 158504-45-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,8,5,0 and 4 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 158504-45:
(8*1)+(7*5)+(6*8)+(5*5)+(4*0)+(3*4)+(2*4)+(1*5)=141
141 % 10 = 1
So 158504-45-1 is a valid CAS Registry Number.
