Check Digit Verification of cas no
The CAS Registry Mumber 127977-72-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,9,7 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127977-72:
(8*1)+(7*2)+(6*7)+(5*9)+(4*7)+(3*7)+(2*7)+(1*2)=174
174 % 10 = 4
So 127977-72-4 is a valid CAS Registry Number.
