119657-53-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119657-53-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,6,5 and 7 respectively; the second part has 2 digits, 5 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119657-53:
(8*1)+(7*1)+(6*9)+(5*6)+(4*5)+(3*7)+(2*5)+(1*3)=153
153 % 10 = 3
So 119657-53-3 is a valid CAS Registry Number.
