1289424-57-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1289424-57-2 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, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1289424-57:
(9*1)+(8*2)+(7*8)+(6*9)+(5*4)+(4*2)+(3*4)+(2*5)+(1*7)=192
192 % 10 = 2
So 1289424-57-2 is a valid CAS Registry Number.
