21784-56-5 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21784-56-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,7,8 and 4 respectively; the second part has 2 digits, 5 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 21784-56:
(7*2)+(6*1)+(5*7)+(4*8)+(3*4)+(2*5)+(1*6)=115
115 % 10 = 5
So 21784-56-5 is a valid CAS Registry Number.
