214826-20-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 214826-20-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,4,8,2 and 6 respectively; the second part has 2 digits, 2 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 214826-20:
(8*2)+(7*1)+(6*4)+(5*8)+(4*2)+(3*6)+(2*2)+(1*0)=117
117 % 10 = 7
So 214826-20-7 is a valid CAS Registry Number.
