74302-07-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74302-07-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,3,0 and 2 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 74302-07:
(7*7)+(6*4)+(5*3)+(4*0)+(3*2)+(2*0)+(1*7)=101
101 % 10 = 1
So 74302-07-1 is a valid CAS Registry Number.
