74954-99-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74954-99-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,5 and 4 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74954-99:
(7*7)+(6*4)+(5*9)+(4*5)+(3*4)+(2*9)+(1*9)=177
177 % 10 = 7
So 74954-99-7 is a valid CAS Registry Number.
