74914-71-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74914-71-9 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 4 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 74914-71:
(7*7)+(6*4)+(5*9)+(4*1)+(3*4)+(2*7)+(1*1)=149
149 % 10 = 9
