Check Digit Verification of cas no
The CAS Registry Mumber 10279-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,0,2,7 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 10279-68:
(7*1)+(6*0)+(5*2)+(4*7)+(3*9)+(2*6)+(1*8)=92
92 % 10 = 2
So 10279-68-2 is a valid CAS Registry Number.
