672903-58-1 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 672903-58-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,2,9,0 and 3 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 672903-58:
(8*6)+(7*7)+(6*2)+(5*9)+(4*0)+(3*3)+(2*5)+(1*8)=181
181 % 10 = 1
So 672903-58-1 is a valid CAS Registry Number.
