921620-91-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 921620-91-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 9,2,1,6,2 and 0 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 921620-91:
(8*9)+(7*2)+(6*1)+(5*6)+(4*2)+(3*0)+(2*9)+(1*1)=149
149 % 10 = 9
So 921620-91-9 is a valid CAS Registry Number.
