213894-77-0 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213894-77-0 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,8,9 and 4 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 213894-77:
(8*2)+(7*1)+(6*3)+(5*8)+(4*9)+(3*4)+(2*7)+(1*7)=150
150 % 10 = 0
So 213894-77-0 is a valid CAS Registry Number.
