213680-79-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 213680-79-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,3,6,8 and 0 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 213680-79:
(8*2)+(7*1)+(6*3)+(5*6)+(4*8)+(3*0)+(2*7)+(1*9)=126
126 % 10 = 6
So 213680-79-6 is a valid CAS Registry Number.
