1435331-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1435331-57-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,3,5,3,3 and 1 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1435331-57:
(9*1)+(8*4)+(7*3)+(6*5)+(5*3)+(4*3)+(3*1)+(2*5)+(1*7)=139
139 % 10 = 9
So 1435331-57-9 is a valid CAS Registry Number.
