21487-27-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21487-27-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,4,8 and 7 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21487-27:
(7*2)+(6*1)+(5*4)+(4*8)+(3*7)+(2*2)+(1*7)=104
104 % 10 = 4
So 21487-27-4 is a valid CAS Registry Number.
