76403-45-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 76403-45-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,6,4,0 and 3 respectively; the second part has 2 digits, 4 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 76403-45:
(7*7)+(6*6)+(5*4)+(4*0)+(3*3)+(2*4)+(1*5)=127
127 % 10 = 7
So 76403-45-7 is a valid CAS Registry Number.
