224645-86-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 224645-86-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,2,4,6,4 and 5 respectively; the second part has 2 digits, 8 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 224645-86:
(8*2)+(7*2)+(6*4)+(5*6)+(4*4)+(3*5)+(2*8)+(1*6)=137
137 % 10 = 7
So 224645-86-7 is a valid CAS Registry Number.
