431979-02-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 431979-02-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,3,1,9,7 and 9 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 431979-02:
(8*4)+(7*3)+(6*1)+(5*9)+(4*7)+(3*9)+(2*0)+(1*2)=161
161 % 10 = 1
So 431979-02-1 is a valid CAS Registry Number.
