922732-20-5 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 922732-20-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,2,7,3 and 2 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 922732-20:
(8*9)+(7*2)+(6*2)+(5*7)+(4*3)+(3*2)+(2*2)+(1*0)=155
155 % 10 = 5
So 922732-20-5 is a valid CAS Registry Number.
