289706-68-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 289706-68-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,8,9,7,0 and 6 respectively; the second part has 2 digits, 6 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 289706-68:
(8*2)+(7*8)+(6*9)+(5*7)+(4*0)+(3*6)+(2*6)+(1*8)=199
199 % 10 = 9
So 289706-68-9 is a valid CAS Registry Number.
