34874-75-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34874-75-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,8,7 and 4 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 34874-75:
(7*3)+(6*4)+(5*8)+(4*7)+(3*4)+(2*7)+(1*5)=144
144 % 10 = 4
So 34874-75-4 is a valid CAS Registry Number.
