215780-07-7 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 215780-07-7 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 2,1,5,7,8 and 0 respectively; the second part has 2 digits, 0 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 215780-07:
(8*2)+(7*1)+(6*5)+(5*7)+(4*8)+(3*0)+(2*0)+(1*7)=127
127 % 10 = 7
So 215780-07-7 is a valid CAS Registry Number.
