34765-76-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 34765-76-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,4,7,6 and 5 respectively; the second part has 2 digits, 7 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 34765-76:
(7*3)+(6*4)+(5*7)+(4*6)+(3*5)+(2*7)+(1*6)=139
139 % 10 = 9
So 34765-76-9 is a valid CAS Registry Number.
