921894-73-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 921894-73-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,1,8,9 and 4 respectively; the second part has 2 digits, 7 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 921894-73:
(8*9)+(7*2)+(6*1)+(5*8)+(4*9)+(3*4)+(2*7)+(1*3)=197
197 % 10 = 7
So 921894-73-7 is a valid CAS Registry Number.
