78045-65-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 78045-65-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,0,4 and 5 respectively; the second part has 2 digits, 6 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 78045-65:
(7*7)+(6*8)+(5*0)+(4*4)+(3*5)+(2*6)+(1*5)=145
145 % 10 = 5
So 78045-65-5 is a valid CAS Registry Number.
