900783-31-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 900783-31-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,0,0,7,8 and 3 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 900783-31:
(8*9)+(7*0)+(6*0)+(5*7)+(4*8)+(3*3)+(2*3)+(1*1)=155
155 % 10 = 5
So 900783-31-5 is a valid CAS Registry Number.
