1609268-90-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1609268-90-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,2,6 and 8 respectively; the second part has 2 digits, 9 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1609268-90:
(9*1)+(8*6)+(7*0)+(6*9)+(5*2)+(4*6)+(3*8)+(2*9)+(1*0)=187
187 % 10 = 7
So 1609268-90-7 is a valid CAS Registry Number.
