Check Digit Verification of cas no
The CAS Registry Mumber 1257902-73-0 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,2,5,7,9,0 and 2 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1257902-73:
(9*1)+(8*2)+(7*5)+(6*7)+(5*9)+(4*0)+(3*2)+(2*7)+(1*3)=170
170 % 10 = 0
So 1257902-73-0 is a valid CAS Registry Number.
