Check Digit Verification of cas no
The CAS Registry Mumber 247584-10-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,4,7,5,8 and 4 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 247584-10:
(8*2)+(7*4)+(6*7)+(5*5)+(4*8)+(3*4)+(2*1)+(1*0)=157
157 % 10 = 7
So 247584-10-7 is a valid CAS Registry Number.
