145375-57-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 145375-57-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,5,3,7 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 145375-57:
(8*1)+(7*4)+(6*5)+(5*3)+(4*7)+(3*5)+(2*5)+(1*7)=141
141 % 10 = 1
So 145375-57-1 is a valid CAS Registry Number.
