322765-99-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 322765-99-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,2,2,7,6 and 5 respectively; the second part has 2 digits, 9 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 322765-99:
(8*3)+(7*2)+(6*2)+(5*7)+(4*6)+(3*5)+(2*9)+(1*9)=151
151 % 10 = 1
So 322765-99-1 is a valid CAS Registry Number.
