112807-67-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 112807-67-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,1,2,8,0 and 7 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 112807-67:
(8*1)+(7*1)+(6*2)+(5*8)+(4*0)+(3*7)+(2*6)+(1*7)=107
107 % 10 = 7
So 112807-67-7 is a valid CAS Registry Number.
