1023889-17-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1023889-17-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,3,8,8 and 9 respectively; the second part has 2 digits, 1 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1023889-17:
(9*1)+(8*0)+(7*2)+(6*3)+(5*8)+(4*8)+(3*9)+(2*1)+(1*7)=149
149 % 10 = 9
So 1023889-17-9 is a valid CAS Registry Number.
