918303-70-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 918303-70-5 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,1,8,3,0 and 3 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 918303-70:
(8*9)+(7*1)+(6*8)+(5*3)+(4*0)+(3*3)+(2*7)+(1*0)=165
165 % 10 = 5
So 918303-70-5 is a valid CAS Registry Number.
