78025-21-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78025-21-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,2 and 5 respectively; the second part has 2 digits, 2 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 78025-21:
(7*7)+(6*8)+(5*0)+(4*2)+(3*5)+(2*2)+(1*1)=125
125 % 10 = 5
So 78025-21-5 is a valid CAS Registry Number.
