Check Digit Verification of cas no
The CAS Registry Mumber 127056-11-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,0,5 and 6 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 127056-11:
(8*1)+(7*2)+(6*7)+(5*0)+(4*5)+(3*6)+(2*1)+(1*1)=105
105 % 10 = 5
So 127056-11-5 is a valid CAS Registry Number.
