74911-94-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74911-94-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,9,1 and 1 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 74911-94:
(7*7)+(6*4)+(5*9)+(4*1)+(3*1)+(2*9)+(1*4)=147
147 % 10 = 7
So 74911-94-7 is a valid CAS Registry Number.
