494750-89-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 494750-89-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,4,7,5 and 0 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 494750-89:
(8*4)+(7*9)+(6*4)+(5*7)+(4*5)+(3*0)+(2*8)+(1*9)=199
199 % 10 = 9
So 494750-89-9 is a valid CAS Registry Number.
