58182-63-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 58182-63-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,8,1,8 and 2 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 58182-63:
(7*5)+(6*8)+(5*1)+(4*8)+(3*2)+(2*6)+(1*3)=141
141 % 10 = 1
So 58182-63-1 is a valid CAS Registry Number.
