143773-19-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 143773-19-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,3,7,7 and 3 respectively; the second part has 2 digits, 1 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 143773-19:
(8*1)+(7*4)+(6*3)+(5*7)+(4*7)+(3*3)+(2*1)+(1*9)=137
137 % 10 = 7
So 143773-19-7 is a valid CAS Registry Number.
