74805-35-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74805-35-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,0 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 74805-35:
(7*7)+(6*4)+(5*8)+(4*0)+(3*5)+(2*3)+(1*5)=139
139 % 10 = 9
So 74805-35-9 is a valid CAS Registry Number.
