29775-74-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 29775-74-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,9,7,7 and 5 respectively; the second part has 2 digits, 7 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 29775-74:
(7*2)+(6*9)+(5*7)+(4*7)+(3*5)+(2*7)+(1*4)=164
164 % 10 = 4
So 29775-74-4 is a valid CAS Registry Number.
