Check Digit Verification of cas no
The CAS Registry Mumber 12007-23-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,0 and 7 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 12007-23:
(7*1)+(6*2)+(5*0)+(4*0)+(3*7)+(2*2)+(1*3)=47
47 % 10 = 7
So 12007-23-7 is a valid CAS Registry Number.
