282725-28-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 282725-28-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,2,7,2 and 5 respectively; the second part has 2 digits, 2 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 282725-28:
(8*2)+(7*8)+(6*2)+(5*7)+(4*2)+(3*5)+(2*2)+(1*8)=154
154 % 10 = 4
So 282725-28-4 is a valid CAS Registry Number.
