556050-48-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 556050-48-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 5,5,6,0,5 and 0 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 556050-48:
(8*5)+(7*5)+(6*6)+(5*0)+(4*5)+(3*0)+(2*4)+(1*8)=147
147 % 10 = 7
So 556050-48-7 is a valid CAS Registry Number.
