213754-96-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213754-96-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,7,5 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 213754-96:
(8*2)+(7*1)+(6*3)+(5*7)+(4*5)+(3*4)+(2*9)+(1*6)=132
132 % 10 = 2
So 213754-96-2 is a valid CAS Registry Number.
