143582-31-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143582-31-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,5,8 and 2 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 143582-31:
(8*1)+(7*4)+(6*3)+(5*5)+(4*8)+(3*2)+(2*3)+(1*1)=124
124 % 10 = 4
So 143582-31-4 is a valid CAS Registry Number.
