Check Digit Verification of cas no
The CAS Registry Mumber 127258-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,7,2,5 and 8 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 127258-12:
(8*1)+(7*2)+(6*7)+(5*2)+(4*5)+(3*8)+(2*1)+(1*2)=122
122 % 10 = 2
So 127258-12-2 is a valid CAS Registry Number.
