216877-12-2 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 216877-12-2 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,6,8,7 and 7 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 216877-12:
(8*2)+(7*1)+(6*6)+(5*8)+(4*7)+(3*7)+(2*1)+(1*2)=152
152 % 10 = 2
So 216877-12-2 is a valid CAS Registry Number.
