19248-36-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19248-36-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,2,4 and 8 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 19248-36:
(7*1)+(6*9)+(5*2)+(4*4)+(3*8)+(2*3)+(1*6)=123
123 % 10 = 3
So 19248-36-3 is a valid CAS Registry Number.
