159116-73-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159116-73-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,1,1 and 6 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 159116-73:
(8*1)+(7*5)+(6*9)+(5*1)+(4*1)+(3*6)+(2*7)+(1*3)=141
141 % 10 = 1
So 159116-73-1 is a valid CAS Registry Number.
