Check Digit Verification of cas no
The CAS Registry Mumber 340041-90-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,4,0,0,4 and 1 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 340041-90:
(8*3)+(7*4)+(6*0)+(5*0)+(4*4)+(3*1)+(2*9)+(1*0)=89
89 % 10 = 9
So 340041-90-9 is a valid CAS Registry Number.
