681430-02-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 681430-02-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,8,1,4,3 and 0 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 681430-02:
(8*6)+(7*8)+(6*1)+(5*4)+(4*3)+(3*0)+(2*0)+(1*2)=144
144 % 10 = 4
So 681430-02-4 is a valid CAS Registry Number.
