90844-48-7 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 90844-48-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,8,4 and 4 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 90844-48:
(7*9)+(6*0)+(5*8)+(4*4)+(3*4)+(2*4)+(1*8)=147
147 % 10 = 7
So 90844-48-7 is a valid CAS Registry Number.
