252672-44-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 252672-44-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,5,2,6,7 and 2 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 252672-44:
(8*2)+(7*5)+(6*2)+(5*6)+(4*7)+(3*2)+(2*4)+(1*4)=139
139 % 10 = 9
So 252672-44-9 is a valid CAS Registry Number.
