1021875-50-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1021875-50-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,1,8,7 and 5 respectively; the second part has 2 digits, 5 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 1021875-50:
(9*1)+(8*0)+(7*2)+(6*1)+(5*8)+(4*7)+(3*5)+(2*5)+(1*0)=122
122 % 10 = 2
So 1021875-50-2 is a valid CAS Registry Number.
