470677-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 470677-99-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,0,6,7 and 7 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 470677-99:
(8*4)+(7*7)+(6*0)+(5*6)+(4*7)+(3*7)+(2*9)+(1*9)=187
187 % 10 = 7
So 470677-99-7 is a valid CAS Registry Number.
