Check Digit Verification of cas no
The CAS Registry Mumber 1609958-23-7 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,6,0,9,9,5 and 8 respectively; the second part has 2 digits, 2 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 1609958-23:
(9*1)+(8*6)+(7*0)+(6*9)+(5*9)+(4*5)+(3*8)+(2*2)+(1*3)=207
207 % 10 = 7
So 1609958-23-7 is a valid CAS Registry Number.
