1657009-87-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1657009-87-4 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,5,7,0,0 and 9 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1657009-87:
(9*1)+(8*6)+(7*5)+(6*7)+(5*0)+(4*0)+(3*9)+(2*8)+(1*7)=184
184 % 10 = 4
So 1657009-87-4 is a valid CAS Registry Number.
