156848-67-8 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 156848-67-8 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,5,6,8,4 and 8 respectively; the second part has 2 digits, 6 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 156848-67:
(8*1)+(7*5)+(6*6)+(5*8)+(4*4)+(3*8)+(2*6)+(1*7)=178
178 % 10 = 8
So 156848-67-8 is a valid CAS Registry Number.
