74835-39-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 74835-39-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,8,3 and 5 respectively; the second part has 2 digits, 3 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 74835-39:
(7*7)+(6*4)+(5*8)+(4*3)+(3*5)+(2*3)+(1*9)=155
155 % 10 = 5
So 74835-39-5 is a valid CAS Registry Number.
