Check Digit Verification of cas no
The CAS Registry Mumber 1023889-38-4 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, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 1023889-38:
(9*1)+(8*0)+(7*2)+(6*3)+(5*8)+(4*8)+(3*9)+(2*3)+(1*8)=154
154 % 10 = 4
So 1023889-38-4 is a valid CAS Registry Number.
