74693-49-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74693-49-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,9 and 3 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74693-49:
(7*7)+(6*4)+(5*6)+(4*9)+(3*3)+(2*4)+(1*9)=165
165 % 10 = 5
So 74693-49-5 is a valid CAS Registry Number.
