76378-44-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76378-44-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,3,7 and 8 respectively; the second part has 2 digits, 4 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 76378-44:
(7*7)+(6*6)+(5*3)+(4*7)+(3*8)+(2*4)+(1*4)=164
164 % 10 = 4
So 76378-44-4 is a valid CAS Registry Number.
