74292-72-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74292-72-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,2,9 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74292-72:
(7*7)+(6*4)+(5*2)+(4*9)+(3*2)+(2*7)+(1*2)=141
141 % 10 = 1
So 74292-72-1 is a valid CAS Registry Number.
