105849-79-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 105849-79-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,5,8,4 and 9 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 105849-79:
(8*1)+(7*0)+(6*5)+(5*8)+(4*4)+(3*9)+(2*7)+(1*9)=144
144 % 10 = 4
So 105849-79-4 is a valid CAS Registry Number.
