1234799-80-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1234799-80-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,3,4,7,9 and 9 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1234799-80:
(9*1)+(8*2)+(7*3)+(6*4)+(5*7)+(4*9)+(3*9)+(2*8)+(1*0)=184
184 % 10 = 4
So 1234799-80-4 is a valid CAS Registry Number.
