74065-85-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74065-85-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,0,6 and 5 respectively; the second part has 2 digits, 8 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74065-85:
(7*7)+(6*4)+(5*0)+(4*6)+(3*5)+(2*8)+(1*5)=133
133 % 10 = 3
So 74065-85-3 is a valid CAS Registry Number.
