470478-33-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 470478-33-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 4,7,0,4,7 and 8 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 470478-33:
(8*4)+(7*7)+(6*0)+(5*4)+(4*7)+(3*8)+(2*3)+(1*3)=162
162 % 10 = 2
So 470478-33-2 is a valid CAS Registry Number.
