928642-48-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 928642-48-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,8,6,4 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 928642-48:
(8*9)+(7*2)+(6*8)+(5*6)+(4*4)+(3*2)+(2*4)+(1*8)=202
202 % 10 = 2
So 928642-48-2 is a valid CAS Registry Number.
