Check Digit Verification of cas no
The CAS Registry Mumber 477807-92-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,7,8,0 and 7 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 477807-92:
(8*4)+(7*7)+(6*7)+(5*8)+(4*0)+(3*7)+(2*9)+(1*2)=204
204 % 10 = 4
So 477807-92-4 is a valid CAS Registry Number.
