674784-72-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 674784-72-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 6,7,4,7,8 and 4 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 674784-72:
(8*6)+(7*7)+(6*4)+(5*7)+(4*8)+(3*4)+(2*7)+(1*2)=216
216 % 10 = 6
So 674784-72-6 is a valid CAS Registry Number.
