155455-48-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 155455-48-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,5,4,5 and 5 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 155455-48:
(8*1)+(7*5)+(6*5)+(5*4)+(4*5)+(3*5)+(2*4)+(1*8)=144
144 % 10 = 4
So 155455-48-4 is a valid CAS Registry Number.
