22932-50-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 22932-50-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,9,3 and 2 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 22932-50:
(7*2)+(6*2)+(5*9)+(4*3)+(3*2)+(2*5)+(1*0)=99
99 % 10 = 9
So 22932-50-9 is a valid CAS Registry Number.
