457930-97-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 457930-97-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,5,7,9,3 and 0 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 457930-97:
(8*4)+(7*5)+(6*7)+(5*9)+(4*3)+(3*0)+(2*9)+(1*7)=191
191 % 10 = 1
So 457930-97-1 is a valid CAS Registry Number.
