229648-91-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 229648-91-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,9,6,4 and 8 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 229648-91:
(8*2)+(7*2)+(6*9)+(5*6)+(4*4)+(3*8)+(2*9)+(1*1)=173
173 % 10 = 3
So 229648-91-3 is a valid CAS Registry Number.
