119421-27-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 119421-27-1 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,9,4,2 and 1 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 119421-27:
(8*1)+(7*1)+(6*9)+(5*4)+(4*2)+(3*1)+(2*2)+(1*7)=111
111 % 10 = 1
So 119421-27-1 is a valid CAS Registry Number.
