1447767-19-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1447767-19-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,4,7,7,6 and 7 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1447767-19:
(9*1)+(8*4)+(7*4)+(6*7)+(5*7)+(4*6)+(3*7)+(2*1)+(1*9)=202
202 % 10 = 2
So 1447767-19-2 is a valid CAS Registry Number.
