150491-23-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 150491-23-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,0,4,9 and 1 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 150491-23:
(8*1)+(7*5)+(6*0)+(5*4)+(4*9)+(3*1)+(2*2)+(1*3)=109
109 % 10 = 9
So 150491-23-9 is a valid CAS Registry Number.
