74644-92-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74644-92-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,6,4 and 4 respectively; the second part has 2 digits, 9 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 74644-92:
(7*7)+(6*4)+(5*6)+(4*4)+(3*4)+(2*9)+(1*2)=151
151 % 10 = 1
So 74644-92-1 is a valid CAS Registry Number.
