104239-15-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 104239-15-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,4,2,3 and 9 respectively; the second part has 2 digits, 1 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 104239-15:
(8*1)+(7*0)+(6*4)+(5*2)+(4*3)+(3*9)+(2*1)+(1*5)=88
88 % 10 = 8
So 104239-15-8 is a valid CAS Registry Number.
