872728-78-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 872728-78-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,7,2,7,2 and 8 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 872728-78:
(8*8)+(7*7)+(6*2)+(5*7)+(4*2)+(3*8)+(2*7)+(1*8)=214
214 % 10 = 4
So 872728-78-4 is a valid CAS Registry Number.
