19039-77-1 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 19039-77-1 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,9,0,3 and 9 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 19039-77:
(7*1)+(6*9)+(5*0)+(4*3)+(3*9)+(2*7)+(1*7)=121
121 % 10 = 1
So 19039-77-1 is a valid CAS Registry Number.
