76945-20-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76945-20-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,9,4 and 5 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 76945-20:
(7*7)+(6*6)+(5*9)+(4*4)+(3*5)+(2*2)+(1*0)=165
165 % 10 = 5
So 76945-20-5 is a valid CAS Registry Number.
