119554-23-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119554-23-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,5,5 and 4 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119554-23:
(8*1)+(7*1)+(6*9)+(5*5)+(4*5)+(3*4)+(2*2)+(1*3)=133
133 % 10 = 3
So 119554-23-3 is a valid CAS Registry Number.
