515172-79-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 515172-79-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,1,5,1,7 and 2 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 515172-79:
(8*5)+(7*1)+(6*5)+(5*1)+(4*7)+(3*2)+(2*7)+(1*9)=139
139 % 10 = 9
So 515172-79-9 is a valid CAS Registry Number.
