101980-03-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 101980-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,1,9,8 and 0 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 101980-03:
(8*1)+(7*0)+(6*1)+(5*9)+(4*8)+(3*0)+(2*0)+(1*3)=94
94 % 10 = 4
So 101980-03-4 is a valid CAS Registry Number.
