672949-03-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 672949-03-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,2,9,4 and 9 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 672949-03:
(8*6)+(7*7)+(6*2)+(5*9)+(4*4)+(3*9)+(2*0)+(1*3)=200
200 % 10 = 0
So 672949-03-0 is a valid CAS Registry Number.
