Check Digit Verification of cas no
The CAS Registry Mumber 345207-68-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,5,2,0 and 7 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 345207-68:
(8*3)+(7*4)+(6*5)+(5*2)+(4*0)+(3*7)+(2*6)+(1*8)=133
133 % 10 = 3
So 345207-68-3 is a valid CAS Registry Number.
