946419-72-3 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 946419-72-3 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,4,6,4,1 and 9 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 946419-72:
(8*9)+(7*4)+(6*6)+(5*4)+(4*1)+(3*9)+(2*7)+(1*2)=203
203 % 10 = 3
So 946419-72-3 is a valid CAS Registry Number.
