Check Digit Verification of cas no
The CAS Registry Mumber 202406-67-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,4,0 and 6 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 202406-67:
(8*2)+(7*0)+(6*2)+(5*4)+(4*0)+(3*6)+(2*6)+(1*7)=85
85 % 10 = 5
So 202406-67-5 is a valid CAS Registry Number.
