1420857-78-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1420857-78-8 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,4,2,0,8,5 and 7 respectively; the second part has 2 digits, 7 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1420857-78:
(9*1)+(8*4)+(7*2)+(6*0)+(5*8)+(4*5)+(3*7)+(2*7)+(1*8)=158
158 % 10 = 8
So 1420857-78-8 is a valid CAS Registry Number.
