Check Digit Verification of cas no
The CAS Registry Mumber 102389-90-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,2,3,8 and 9 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 102389-90:
(8*1)+(7*0)+(6*2)+(5*3)+(4*8)+(3*9)+(2*9)+(1*0)=112
112 % 10 = 2
So 102389-90-2 is a valid CAS Registry Number.
