343982-18-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 343982-18-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,3,9,8 and 2 respectively; the second part has 2 digits, 1 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 343982-18:
(8*3)+(7*4)+(6*3)+(5*9)+(4*8)+(3*2)+(2*1)+(1*8)=163
163 % 10 = 3
So 343982-18-3 is a valid CAS Registry Number.
