Check Digit Verification of cas no
The CAS Registry Mumber 657409-74-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,5,7,4,0 and 9 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 657409-74:
(8*6)+(7*5)+(6*7)+(5*4)+(4*0)+(3*9)+(2*7)+(1*4)=190
190 % 10 = 0
So 657409-74-0 is a valid CAS Registry Number.
