119458-83-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119458-83-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,4,5 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 119458-83:
(8*1)+(7*1)+(6*9)+(5*4)+(4*5)+(3*8)+(2*8)+(1*3)=152
152 % 10 = 2
So 119458-83-2 is a valid CAS Registry Number.
