74444-67-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74444-67-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,4 and 4 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74444-67:
(7*7)+(6*4)+(5*4)+(4*4)+(3*4)+(2*6)+(1*7)=140
140 % 10 = 0
So 74444-67-0 is a valid CAS Registry Number.
