141794-49-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 141794-49-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,7,9 and 4 respectively; the second part has 2 digits, 4 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 141794-49:
(8*1)+(7*4)+(6*1)+(5*7)+(4*9)+(3*4)+(2*4)+(1*9)=142
142 % 10 = 2
So 141794-49-2 is a valid CAS Registry Number.
