212388-61-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 212388-61-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,2,3,8 and 8 respectively; the second part has 2 digits, 6 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 212388-61:
(8*2)+(7*1)+(6*2)+(5*3)+(4*8)+(3*8)+(2*6)+(1*1)=119
119 % 10 = 9
So 212388-61-9 is a valid CAS Registry Number.
