Check Digit Verification of cas no
The CAS Registry Mumber 300680-47-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,0,6,8 and 0 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 300680-47:
(8*3)+(7*0)+(6*0)+(5*6)+(4*8)+(3*0)+(2*4)+(1*7)=101
101 % 10 = 1
So 300680-47-1 is a valid CAS Registry Number.
