855254-49-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 855254-49-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,5,5,2,5 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 855254-49:
(8*8)+(7*5)+(6*5)+(5*2)+(4*5)+(3*4)+(2*4)+(1*9)=188
188 % 10 = 8
So 855254-49-8 is a valid CAS Registry Number.
