19233-57-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19233-57-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,3 and 3 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19233-57:
(7*1)+(6*9)+(5*2)+(4*3)+(3*3)+(2*5)+(1*7)=109
109 % 10 = 9
So 19233-57-9 is a valid CAS Registry Number.
