470666-98-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 470666-98-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,0,6,6 and 6 respectively; the second part has 2 digits, 9 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 470666-98:
(8*4)+(7*7)+(6*0)+(5*6)+(4*6)+(3*6)+(2*9)+(1*8)=179
179 % 10 = 9
So 470666-98-9 is a valid CAS Registry Number.
