112157-48-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112157-48-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,1,5 and 7 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 112157-48:
(8*1)+(7*1)+(6*2)+(5*1)+(4*5)+(3*7)+(2*4)+(1*8)=89
89 % 10 = 9
So 112157-48-9 is a valid CAS Registry Number.
