Check Digit Verification of cas no
The CAS Registry Mumber 20749-68-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,7,4 and 9 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 20749-68:
(7*2)+(6*0)+(5*7)+(4*4)+(3*9)+(2*6)+(1*8)=112
112 % 10 = 2
So 20749-68-2 is a valid CAS Registry Number.
