Check Digit Verification of cas no
The CAS Registry Mumber 1020848-83-2 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,0,2,0,8,4 and 8 respectively; the second part has 2 digits, 8 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1020848-83:
(9*1)+(8*0)+(7*2)+(6*0)+(5*8)+(4*4)+(3*8)+(2*8)+(1*3)=122
122 % 10 = 2
So 1020848-83-2 is a valid CAS Registry Number.
