491838-02-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 491838-02-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,9,1,8,3 and 8 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 491838-02:
(8*4)+(7*9)+(6*1)+(5*8)+(4*3)+(3*8)+(2*0)+(1*2)=179
179 % 10 = 9
So 491838-02-9 is a valid CAS Registry Number.
