1242190-05-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1242190-05-1 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,4,2,1,9 and 0 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1242190-05:
(9*1)+(8*2)+(7*4)+(6*2)+(5*1)+(4*9)+(3*0)+(2*0)+(1*5)=111
111 % 10 = 1
So 1242190-05-1 is a valid CAS Registry Number.
