The CAS Registry Mumber 649713-06-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,4,9,7,1 and 3 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 649713-06:
(8*6)+(7*4)+(6*9)+(5*7)+(4*1)+(3*3)+(2*0)+(1*6)=184
184 % 10 = 4
So 649713-06-4 is a valid CAS Registry Number.
