226547-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 226547-35-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,6,5,4 and 7 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 226547-35:
(8*2)+(7*2)+(6*6)+(5*5)+(4*4)+(3*7)+(2*3)+(1*5)=139
139 % 10 = 9
So 226547-35-9 is a valid CAS Registry Number.
