1645-69-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 1645-69-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,4 and 5 respectively; the second part has 2 digits, 6 and 9 respectively.Calculate Digit Verification of CAS Registry Number 1645-69:
(6*1)+(5*6)+(4*4)+(3*5)+(2*6)+(1*9)=88
88 % 10 = 8
So 1645-69-8 is a valid CAS Registry Number.
