Check Digit Verification of cas no
The CAS Registry Mumber 801243-60-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,0,1,2,4 and 3 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 801243-60:
(8*8)+(7*0)+(6*1)+(5*2)+(4*4)+(3*3)+(2*6)+(1*0)=117
117 % 10 = 7
So 801243-60-7 is a valid CAS Registry Number.
