21187-77-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 21187-77-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,1,1,8 and 7 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 21187-77:
(7*2)+(6*1)+(5*1)+(4*8)+(3*7)+(2*7)+(1*7)=99
99 % 10 = 9
So 21187-77-9 is a valid CAS Registry Number.
