Check Digit Verification of cas no
The CAS Registry Mumber 147285-79-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,7,2,8 and 5 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 147285-79:
(8*1)+(7*4)+(6*7)+(5*2)+(4*8)+(3*5)+(2*7)+(1*9)=158
158 % 10 = 8
So 147285-79-8 is a valid CAS Registry Number.
