159955-40-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159955-40-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,9,5 and 5 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 159955-40:
(8*1)+(7*5)+(6*9)+(5*9)+(4*5)+(3*5)+(2*4)+(1*0)=185
185 % 10 = 5
So 159955-40-5 is a valid CAS Registry Number.
