154491-48-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 154491-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,4,4,9 and 1 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 154491-48:
(8*1)+(7*5)+(6*4)+(5*4)+(4*9)+(3*1)+(2*4)+(1*8)=142
142 % 10 = 2
So 154491-48-2 is a valid CAS Registry Number.
