1289424-48-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1289424-48-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,8,9,4,2 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1289424-48:
(9*1)+(8*2)+(7*8)+(6*9)+(5*4)+(4*2)+(3*4)+(2*4)+(1*8)=191
191 % 10 = 1
So 1289424-48-1 is a valid CAS Registry Number.
