Check Digit Verification of cas no
The CAS Registry Mumber 307551-24-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 3,0,7,5,5 and 1 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 307551-24:
(8*3)+(7*0)+(6*7)+(5*5)+(4*5)+(3*1)+(2*2)+(1*4)=122
122 % 10 = 2
So 307551-24-2 is a valid CAS Registry Number.
