120869-70-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 120869-70-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,0,8,6 and 9 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 120869-70:
(8*1)+(7*2)+(6*0)+(5*8)+(4*6)+(3*9)+(2*7)+(1*0)=127
127 % 10 = 7
So 120869-70-7 is a valid CAS Registry Number.
