288378-55-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 288378-55-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,8,3,7 and 8 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 288378-55:
(8*2)+(7*8)+(6*8)+(5*3)+(4*7)+(3*8)+(2*5)+(1*5)=202
202 % 10 = 2
So 288378-55-2 is a valid CAS Registry Number.
