831239-07-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 831239-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 8,3,1,2,3 and 9 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 831239-07:
(8*8)+(7*3)+(6*1)+(5*2)+(4*3)+(3*9)+(2*0)+(1*7)=147
147 % 10 = 7
So 831239-07-7 is a valid CAS Registry Number.
