Check Digit Verification of cas no
The CAS Registry Mumber 5979-27-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,7 and 9 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 5979-27:
(6*5)+(5*9)+(4*7)+(3*9)+(2*2)+(1*7)=141
141 % 10 = 1
So 5979-27-1 is a valid CAS Registry Number.
