Check Digit Verification of cas no
The CAS Registry Mumber 824395-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,2,4,3,9 and 5 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 824395-67:
(8*8)+(7*2)+(6*4)+(5*3)+(4*9)+(3*5)+(2*6)+(1*7)=187
187 % 10 = 7
So 824395-67-7 is a valid CAS Registry Number.
