Check Digit Verification of cas no
The CAS Registry Mumber 203307-27-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,0,3,3,0 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 203307-27:
(8*2)+(7*0)+(6*3)+(5*3)+(4*0)+(3*7)+(2*2)+(1*7)=81
81 % 10 = 1
So 203307-27-1 is a valid CAS Registry Number.
