227466-63-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 227466-63-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,7,4,6 and 6 respectively; the second part has 2 digits, 6 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 227466-63:
(8*2)+(7*2)+(6*7)+(5*4)+(4*6)+(3*6)+(2*6)+(1*3)=149
149 % 10 = 9
So 227466-63-9 is a valid CAS Registry Number.
