Check Digit Verification of cas no
The CAS Registry Mumber 602277-55-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,0,2,2,7 and 7 respectively; the second part has 2 digits, 5 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 602277-55:
(8*6)+(7*0)+(6*2)+(5*2)+(4*7)+(3*7)+(2*5)+(1*5)=134
134 % 10 = 4
So 602277-55-4 is a valid CAS Registry Number.
