1627-87-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 1627-87-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,6,2 and 7 respectively; the second part has 2 digits, 8 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1627-87:
(6*1)+(5*6)+(4*2)+(3*7)+(2*8)+(1*7)=88
88 % 10 = 8
So 1627-87-8 is a valid CAS Registry Number.
