Check Digit Verification of cas no
The CAS Registry Mumber 81684-70-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,6,8 and 4 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 81684-70:
(7*8)+(6*1)+(5*6)+(4*8)+(3*4)+(2*7)+(1*0)=150
150 % 10 = 0
So 81684-70-0 is a valid CAS Registry Number.
