Check Digit Verification of cas no
The CAS Registry Mumber 202467-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,2,4,6 and 7 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 202467-70:
(8*2)+(7*0)+(6*2)+(5*4)+(4*6)+(3*7)+(2*7)+(1*0)=107
107 % 10 = 7
So 202467-70-7 is a valid CAS Registry Number.
