159124-49-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 159124-49-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,9,1,2 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 159124-49:
(8*1)+(7*5)+(6*9)+(5*1)+(4*2)+(3*4)+(2*4)+(1*9)=139
139 % 10 = 9
So 159124-49-9 is a valid CAS Registry Number.
